Skarn

Skarn are strong, sophisticated warriors of intellect. Like the rilkans, they are descended from the vanished mishtai progenitor race, which long ago infused all mishtai with incarnum in an attempt to achieve perfection of form. Skarn appear human except for the five or six vertically aligned reptilian spines that project from the anterior of each forearm, posterior of each calf, and the upper back. Skarn society is insular and demands both mental and physical achievement. They are a proud race - some would say arrogant - and they boast soulborns, paladins, rangers, and fighters of other hybrid classes that exemplify perfection of both mind and body.
