I managed to trade for Kirr for +1300 in the end. The respawn point was poor, with the exit leading through a narrow passage on the way to the monolith entrance, and then to the bugged snow golem, where there was noticeable pressure from a rival who had already sneaked in, and also my own lack of funds. But another branch with a narrow passage led to a rich treasure room. The red faction built a resurrection altar with a portal, but they didn't have time to use it - they were outplayed, and their units, unaccustomed to battles, were weak. Thanks for the game.
