Carnonon

This species is superficially identical to humans except for the horns that grow on their head. There are always two, but the style of horn varies. Rams' horns, stags' horns and cows' horns are common. This species is common in the Coastal Safe Zone and the Archipelagic Safe Zone, rarer in the Central Safe Zone and unheard-of in the Northern Safe Zone. Carnonon from the coast often file their horns down for practical reasons, so they can wear standard helmets and other headgear.
The species grants an innate understanding of one Circle of magic associated with a natural elements, such as air magic or stone magic, and grants additional Circle-specific mana of that type. It also allows non-spell-casters access to Perks that take advantage of that supply of mana, so it useful to any Class.
