Any more info on Alchiere?

Just trying to see if there’s any more info on Alchiere out there. I’ve found almost nothing.

Is Into the Deep Wild a good Place to look? It mentions it a little, so maybe? And I think I see some artwork for a painted troll?

If so, is it a good book for someone who really just wants to learn more about the lore, or is it more just the nuts and bolts of how to run an campaign in this setting?

Wondering as a non-rpg player who is more interested in the lore of this area.
