Scalene

I'm planning to do a game for six or so players set in a castle in the Empire. The castle's inhabitants are woken up by Skaven pouring out of every cellar and grating. Men-at-arms, cooks, blacksmiths grab whatever is to hand and try to defend themselves - a sort of zombie apocalypse theme but with Skaven instead of zombies. Aiming to do it on a big table, probably covering two blocks - i.e. 6 hours.
