Traits

In some Xeros, the tapetum lucidum that gives them such excellent low-light vision undergoes a dramatic mutation. Bright pupils are the result of this highly reflective tissue, causing it to reflect in such a manner to create this striking appearance! This trait allows a Xero's pupils to be lighter in color than the iris (the main colored part of the eye). The bright pupils can be any color, so long as they are lighter in value than the iris.
