[Dungeon Master2]

Help me! have just completed the House of Gems area where you had to destroy the spawn pool in order to talk to Harldain Ironbar. 2 questions tho. 1st when does he give you the Gem of the Weave? and 2nd how do I get the Tumblerbar to use on the broken statue? There is supposed to be an encounter at the House of Gems (exterior area #8) with AZMARK DUATHEL and his doomkin cult fighters that is not initializing when I leave. Do I need to do something special here? Pls rsvp asap with any help on this matter
