we have already played the age of worms. the other suggestions sound ok, but the guys like the theme of undead hunters. they all joined the lightbringer guild as listed in ETCR, and i'd like to continue with the same path. I would like to check out Maure castle, what edition is that in? maybe I can morph that with Catacomb of the Scion from Libra Mortis.
any other ideas?
