Hello. New to Blackmoor.

Tinker gnomes like in Dragonlance, no.

Think more in terms of Wilderlands gnomes, ifyaknowwhatimean. Hobbits without the hairy feet, so to speak.

Also useful for this could be the way the "Kingdoms of Kalamar" setting treats gnomes.
If I wanted to insert gnomes into my campaign, I would use that model, I think.
