Some Design Notes:
Gerran is 4'2 - which is average for his race.
He's rarely seen wearing "street" clothes - almost always wears some sort of wizardly garb.
His tail is crooked at the end.

Wanted to make a reference of some kind for Gerran - not sure I'm final on the last name yet, but it's appropriately wizardly for the moment.

In my canon/fiction, felines are typical the smart types- scholars, tinkers, inventors, and wizards. Gerran is one of the best and brightest too.

Spending years studying a wide variety of schools of magic ranging from simple elemental magics to complex runic magics.

His studies and practice into time magic have had some side effects - splitting his personality in two - his younger self, eager to learn all there is about magic, and his older self, set out to find and protect magical artifacts.
