Njord

Njord is completely blind, but he gets a vague idea of his surroundings by creating wind around himself and feeling the way it moves. If you step in his bubble, expect it to be windy. He does the same thing with water when he's underwater. 

Njord comes from a powerful lineage of air elementalists. This specific group learned a way to pass down all of their memories and knowledge onto the next generation. Njord has access to generations of nomad knowledge and sometimes uses it to prank his friends.
