Gnomish twins happen maybe once in a generation, so the extended family came to Erdgeist when Enid and Glimmer drew their first breaths. Glimmer kept wandering over to the Citadel in Erdgeist to watch the dwarven elite warriors practice weapons. He fell in with a few roguish dwarves also hanging around, and they proceeded to get each other in trouble incessantly. Enid ended up keeping an eye on Glimmer to try and keep him out of trouble, but she couldn't be everywhere at once.
The family moved to Aldunleigh so Glimmer's parents could tinker and work for various Dunhill merchants. Erdgeist had dark beer, but Dunhill had strong whiskey. Glimmer left Enid to her studies and found the worst dens of layabouts and troublemakers to entertain himself. He's not dumb, but the humans the he though were friends managed to outmaneuver him, and he took the blame for a jewelry heist even though he wasn't involved at all. He got wind of his impending arrest and went to Enid to say goodbye. To his surprise, she volunteered to go with him.
