I’ve been asked a couple of times to give more details about the actually rules, etc used during the sessions, but since I didn’t want to break up the narrative I thought that i’d separate this stuff out into it’s own post, let me know what you think.
The original post can be found here
With the second wave of enemy ships approaching Lord Admiral Black looked around at the ragged remnant of his fleet and took stock of the force that he has to take on the encroaching heretics, his flagship, the Venerus, was largely untouched (aside from some minor cosmetic damage), the Lunatic Pandorawas functional but had sustained heavy damaged and the Rod Hant was currently fighting off boarders from the first wave of the enemy, and they had only a couple of days before the mainstay of Lorgar Khan’s fleet arrived.
Each of the ships used in this combat had a series of stress boxes worth 1 stress and no consequences; medium ships has three such boxes, with larger ships having four and extremely large ships having five. The ships broke down as follows:
Venerus (players flagship)    
Lunatic Pandora (players)   
Clan ships (including the Rod Hant + the enemy clan ships)   
Dark Omen (traitor space marine battle barge)     
The Venerus has been established as having an elite crew previously in the game so received a +2 bonus to attack/defence rolls, the Rod Hant was severely damaged in the previous combat and so received a -2 to attack/defence rolls.
The Dark Omen is also crewed by elites and so received a +2 bonus to attack and defence rolls.
Over the course of the first day Admiral Black helped Captain Pak repel the boarders on the Rod Hant and eventually they succeeding in killing the last one, although a lengthy check for sabotage and explosives did means that they did not have time to fully repair the extensive damage that the Rod Hant had sustained in the previous combat. Realising that, in their present shape, they could not hope to challenge the mighty Battle Barge of the traitor AstartedLorgar Khan they concocted a desperate plan whereby they would use the ancient teleportarium aboard the Venerus to teleport a fire-linked collection of krak missiles and other explosives into the engine room of the enemy vessel.
The players were offered the choice of thoroughly ensuring that the Rod Hant was free of sabotage, but in return not having time to repair it (and taking a -2 penalty in the fight) or repairing it but potentially having some saboteurs or explosives on board (that may have been used for compels later); knowing that the fight was going to be a close one they chose the former option.
As they readied themselves for combat on the second day, Admiral Black sat on the bridge watching the approaching fleet, his wife at his side and placed his head in his hands; suddenly he was no longer on the bridge of the Venerus but was standing in the royal chambers on his homeworld of Telec Prime, groups of panicked medical technicians were running down a corridor towards a room that he recognised as belong to his father Macharius Black, almost without thinking the Admiral followed them. In the room Macharius, looking sickly, his eyes yellowed and his face (which bore a striking resemblance to that of the Admiral) pale, he was railing against the med-techs who appeared to be informing him that his treatments were no longer proving effective; shouting that there was none to take his place leading the family if he died, Macharius ordered them to send for his sons, there must be other technology out there that could preserve his life.
One of the established character Aspects of Lord Admiral Fortunus Black is that he suffers from blackouts; the player was offered a fate point to reveal some of the plot using this Aspect and accepted leading to the above scene unfolding.
A voice called out to Admiral Black and he jerked awake in the command chair, his wife Lady Dominique Decusis-Black was shaking his arm and looking at him in a concerned manner, but he waved away her concerns saying that he was fine. Captain Pak had finished adapting one of the damaged murder servitors from the Lunatic Pandora and had wired it into the trigger mechanism of the bomb that they had constructed, as the first enemy ships entered range and began to open fire with macro-batteries Pak began to have the teleportarium chamber prepped for dispatch; Navigator York Benetec had been psychically scanning the area and relayed the coordinates for the likely location of the engine room about the enemy battle barge.
The Venerus was discovered and salvaged in-game with an archeotech teleportarium aboard it, this has been modelled in Fate using a Stunt that once per game session allows them to teleport a small party (or the equivalent mass) from anywhere within the same system to the Venerus or from the Venerus to anywhere in the system (that they have the coordinates to). In desperation the players decided to use it to transport a large amount of explosives aboard the approaching battle barge, their tech (Captain Pak) was required to make some risky rolls to connect them all up without explosive results, but he easily passed them.
As his mind probed the area of space around them, Benetec felt another presence and, sensing that it was not hostile, allowed it to make contact with him; Benetec found himself on a prosperous world of fluted silver towers and happy people, the hazy psychic projection of the chaos sorceror Kantor Pilusfloating next to him. Pilus showed Benetec how his homeworld had been devastated by the Astartes after their leader had attempted to use forbidden sorcery to warn the Emperor of treachery from within, “although we were right, this was our reward” mocked the sorceror with a touch of sadness in his voice. Pilus attempted to persuade Benetec that if they just handing the ancient recording device to Lorgar that much bloodshed could be avoided, Benetec refused and broke off the psychic connection.
York Benetec’s player was offered a fate point to reveal some of the plot (in a manner similar to the blackout earlier) and accepted; this scene was RP entirely sans-dice and was more about the choices that the player would make.
The space around Strive filled with escape pods and short range craft as the survivors of ruined ships on both sides sort to make their way planet side; the remaining enemy clan ship attempted to flee, laying mines to cover it’s tracks but it was destroyed by the Venerus, York Benetec was able to use his psychic powers to direct the ships mine defence lasers to target and take out the remaining mines. Meanwhile the Rod Hant had picked up a signal coming from an escaped enemy shuttle that was recognisably Adpetus Mechanicus in origin, moving to intercept, Captain Pak discovered onboard the rogue tech Vorl whom they had previously (on the insistence of the Vitanteur Syndicate) ferried to Footfall from Hiveworld Decusis; Vorl claimed to have been captured on an enemy raid and to have pretended to defect, in his gratitude at having been rescued he revealed Lorgar intended to use the ancient recording device to locate something in the system that would allow some sort of “rebirth.”
The actual combat was played out identically to a normal combat (using attack/defence rolls) with the two elite crewed ships going first and the rest following in no particular order (I generally went player ships first and then enemy ships), each point of stress taken ticked off one of the ships stress boxes. Players were allowed to spend their fate points to re-roll/boost their rolls for ships that their characters were on, as long as they had an appropriate Aspect; this mainly came into play with Admiral Black since his Aspects are mostly based around being a ship’s Captain and they pretty much allowed the Venerus to come through the combat unscathed.
Due to the speed of the vessels involved and the distances under consideration I did not use zones in this combat simply alerting the players when the enemy ships were entering range; the Venerus had moved to the other side of the moon to conceal itself, I had Admiral Black make a command roll against the command roll of Lorgar Khan, the players won and thus were not spotted until too late.
A fate point was offered for an additional complication and, when accepted, this lead to the pickup of the Adeptus Mechanicus signal from the rogue-tech Vorl and some additional information about Lorgar Khan’s goals being revealed.
Relaying this information to Admiral Black, Captain Pak headed down to planet in a landing craft and began broadcasting a signal to draw any survivors from the Lunatic Pandora to them, as they began to arrive in dribs and drabs he was happy to see that Captain Polaris had survived (apparently after a crew member had knocked him out and put him in an escape pod); however the surface of the planet was rapidly coming a war zone as the survivors from both sides began to battle through the streets.
Because it didn’t seem very interesting to just rule that everyone was dead (and as a lead in to the next session) I rules that a lot of people would have made it to escape vessels and would be heading for the nearby moon of Strive (where the player characters spent much of the previous session).
This nicely sets up a battlezone style scenario for the next game and allows for a more satisfying confrontation with the enemy other than just blowing up his ship (whilst still rewarding the players for their inventiveness with the teleportarium, since they have deprived Lorgar Khan of much of his mobility).
