Irl my name is ridiculously common, so it's nearly impossible to choose a decent variation as a tag. Koloblicin is a name meaning "strong advisor" in Terry Goodkind's Sword of Truth series. Those books helped me find a measure of confidence in HS, and I've found myself as one whom my friends often come to for advice, so it fits. Coming full circle, it's uncommon enough that I never get that stupid "name already taken" message. Easily shortened to Kolo in game, and any Goodkind fans can identify in the wider world.
