In the same cave as Ulfar, there's one of the Drust Steles for Drust the Facts, Ma'am. It describes Drust druids showing respect to two forest gods (a giant stag and doe) and getting a favor in return. The deer are Athair and Athainne, which are apparently Irish for "father" and "spark/torch". They can be found upriver from Fallhaven, patrolling in a circle. Athair is chattable, but says nothing (only "regards you") when you chat him on a hunter. He lets druids set their hearthstone though. His title is "Heart of the Forest", and Athainne's is "Secret Keeper of the Forest". So that's kind of hopeful. They pause once in their patrol, and doing supplication type emotes, /bow /kneel /offer, doesn't trigger anything. She apparently changes location during daytime.I suppose you're seeking a new pet?
The magic of this place is deep and profound. It has come to inhabit some of the animals of the region. They are powerful manifestations of nature to be respected.
I checked the rest of the steles, in case that was a condition for triggering something. It didn't help yet (I'm also not 120), but I did learn more about the Drust that may be helpful. There's a lot of human and/or animal sacrifices (Construct, Sacrifice, Circle, Ritual, Flayed Man). Some of the steles seem to point to the location of other steles, but some of them don't. At least one of them is near a sacrifice altar (Cycle). And along the way I found a toy called Drust Ritual Knife which requires a recently killed player character corpse. I haven't test it yet, either at the sacrifice altar, at Athair/Athainne, or anywhere.
Also, I had Tirasreli Gourmet Chocolate in my bag. I doubted it would do anything, but maybe Athainne could have been a chocoholic. My next round of testing will be after I get to 120. In the meantime, I'm keeping my eyes open for entrails, heads, ritual circles (of stones?), and stone slabs with a big grove and lots of blood.
