Level 3 canonical magic users

Based on the Raven’s Purge campaign, this is my understanding of which NPCs are guaranteed to be potential level 3 teachers of magic talents:

Druids:

• Path of Healing: Keldra the Deserving in Pelagia, Rain and Soul in Pelagia
• Path of Shifting Shapes: Merigall, Virelda Bloodbeak, Tarna in Haggler’s House, Merigolene in Eye of the Rose
• Path of Sight: Virelda Bloodbeak, Kalman Rodenfell, Kritre the Caller of Pelagia

Sorcerers:

• Path of Blood: Zytera, Merigall, Kartorda, Ravil of Pelagia
• Path of Death: Zytera, Merigall, Kartorda, Corpse herder Brenziga of Zytera’s Mogarium
• Path of Signs: Merigall
• Path of Stone: ???

The answer to “who do PCs seek out if they want to learn level 3 of the path of stone” is probably “genuinely any high-ranking dwarf”, but I wanted to check whether I’d missed anything out.

“There’s this other good campaign that you could combine with Raven’s Purge” is also an acceptable answer.
