Shark Totem Spirit

Like a shark's fin knifing a straight path through murky waters, barbarians of the Shark Totem approach battle with the calm and unnerving ruthlessness of the oceans' apex predator.
Bloodthirsty and deathly, only the unwise does not fear the the coastal and island tribes that have chosen the shark as their totem animal.

Shark Totem Barbarians around the Azure Sea

It is only natural that those barbarians who follow beast totems close to the waters of The Azure Sea would be drawn to the shark as a spirit animal. In fact, they are one of the most common types of barbarian who have chosen the path of a totem animal.
Non-Carcharions of this primal path are some of the few who are tolerated, if not welcomed, around the waters of the Sharkhan Mangroves, and some have even venture into the coral tube city of Coaria and emerged to tell the tale.
The Shark Totem Spirit is based on original work by Eventyr Games.
