Traits

Horns are a rare trait for a Xero to have; these keratin-covered bones grow in pairs from the top of the Xero's head. Much like the antennae, horns can be many different shapes and lengths. Horns can only be found in symmetrical pairs and only on the top of the Xero's head; for keratinous growths on other areas of the Xero's body, see the Spines trait.
