The Priestess and I snapped out of our rage. We turned back around, safe in the knowledge that the Psyker's power only lasted for a single turn, and then immediately jumped aboard our ship, and blasted off. We made it.
And then the ship's batteries came online, and blew us to kingdom come.
But it doesn't end there. Naturally, we remaining players started packing up, sighing, and staring forlornly at our character sheets.
And then I noticed something. An item, on my sheet, that I had never used before. A Talisman (I forget the proper name)--an article of faith, in this case a bolter shell casing from a DeathWatch boltgun, that would, on GM's permission, allow a character to be exempt from an unfortunate fate that befell his fellows. Naturally, as I'd rather risk death by space than guaranteed death by laser, I immediately pointed this out to the GM, and after some rules clarification, he said he would allow me to be saved by this item.
The Priestess' player, seeing a chance, immediately looked at her character sheet. She had one, too. Psyker Pieren's player looked down at the sheet for her character, but Pieren, the poor Psyker, did not.
The GM grinned his foulest grin. He gazed at us for a few seconds, and then, laughing, told us that, fine, we had earned the Emperor's favor. We deserved something from the Talismans we carried. And, he promised, we would survive. Two of us would, that is; after all, there were only two Talismans, and some kind of price had to be paid. And it would be up to us, the players, to decide amongst ourselves who would live and who would die.
I looked back at the GM, and grinned. I knew the heart of "Bones" Guilliman. I knew exactly what he would do.
"Bones stands up, inside the ship, and, screaming "FOR THE EMPEROR," dives headfirst into the laser beam... or whatever he needs to do to save the other two."
