I really like how both PISORF and ENDISWAL were in the chamber, the only thing that would have made that funnier is if Binlor were in there too and if that subdungeon were Pen. That said, that looks painful.
That's one heck of a secret subdungeon on the pic there ô_o
Pen a halfdragon who gives you PISORF in a subdungeon - I think I've listed it recently on the subdungeon thread. Though to my knowledge, its a subdungeon in the west, so no chance of that being in there.
