Trainer locations

[Gnollmar]

So I just found a trainer location I didn't expect, so why not just make a thread entirely for this?

Thievery training: Troublesome attacked caravan (The one saying "give me your money" gives training.)

Pyromancy training:
Any town with this building has trainers.

Adventuring trainer:
Soldiers in barracks (humans?) can have this.

Yes. But its also a spoiler :)
