Kvallen was raised in Chillblight -- metropolis of the dark, cold fey. And he doesn't talk about it. Ever. There are scars on his body from frostbite and from small, thin knives, and he doesn't talk about those either. Or where he learned to operate siege weapons, or how he got to Absalom.
He does talk about stone, and building structures that will stand for decades. And every exasperating thing his wife Maricelli ever did, and how she was the best person he had ever met. And that he knows that every time the sun sets, she is personally putting the orange in the sky.
He restored the building that currently houses the gallery, and oversees its maintenance and expansion, as well as its physical security.
