Thanks for the help. Not really a new face to Spiderweb Software - I started with Exile 2, in the 1990s and also played Nethergate and Avernum before getting too busy with kids. Now that they're older, I have found time to play epic RPGs from Spiderweb again and am doing Avernum 4-6.
In Avernum 5, I was doing the mission for the stone circle by the drake pillars. Since it said the incantor didn't want the magic destroyed, I let the golem live and returned to town. Apparently, this did not complete the mission. When I went back, both the stone column and the golem are gone. Have I blown any chance to complete this mission? And does this prevent me from getting to Solberg's area??
