Journey

I made it to the mausoleum during Konstantin's campaign. I completed all the quests except for the ones involving bears, the thief, the Tear of Ashera, and the astral gate (5th dwelling). I hit a dead end, haven't encountered the Law, and have no idea where to steal the artifacts. I've explored all the accessible parts of the dungeon and all the castles except for the Temple of the Elements; I can only clear them with the Sword unit and the yellow tent. On the surface, I've cleared everything. How do I get to the part of the dungeon located near the starting castle? Where should I go and what should I do?

Take the quest for the thief. Cross to the other side (5th dwelling) (or just defeat the mummies;) ) and go into the dungeon. There you will find the Law and the second Necromancer, who will help you with the mausoleum.
