Voice actor: Orion Acaba

(taken from wiki entry)

Kellam is a frontline fighter of Chrom's Shepherds and is one of the biggest and tallest units in the army. Despite this, he virtually goes unnoticed. Most of the army considers him a "ghost", as his supports with Robin show that the other members wonder why there is always an extra cup or seat lying around when everyone is supposedly accounted for. 

His lack of presence causes most people to jump in surprise when he suddenly "appears" out of nowhere. He is somewhat irked about this, but he is used to it. The roster states that he is actually quite proud of this. Still, he searches for a way to make others notice him. Interestingly, only those with animal-like senses, like Nowi and Panne, are able to find him rather easily.
