Ax is a mygnin from Caprinica who followed Pommel on her journey towards the great continent of Wurlskar!

Wow that's a lot of words uhh

Mygnins are basically goblin dwarves. They build great underground citadels, and do a lot of mining and crafting. Their fists are as powerful as adamantium, allowing them to hold melting metal, punch through stone, and carve gems with just their fingers!

Ax wasn't really a miner though, he was a soldier, a caprinican one! Just look at that swag-filled muscle armor, and that SKIRT!

He wields an axe (obviously) but instead of holding it by a handle, he just holds the axe head in his hand, swinging it around like some sort of chopping machine!
