Mountain Fort and Stone (Gothic)

I become human and Gomez immediately got the first task and went to the Swamp Camp. Along the way I snapped and killed all these Krovosos and Harpies, explored the Fort. Found the Blue Stone, which conjured barrier and Testament. Returned to their Camp, turned to the mages, but conversations about these things are not there. I went to read. Turns out I was supposed to meet Lester a seeker will. In short, apparently I had climbed.
Question: What to do with the will and Stone, and where to find Lester?
