Viking is a Viking. His dad was either not very creative when it came to naming him, or had a very specific plan for his life. In his story we meet evil giants, awesome mythological dwarf dads, and the only Viking ball game that doesn't turn deadly...during the ball game. It kind of does immediately afterward, though.
The creature is Hogboy! It's a barrow-wight, and it's actually way more terrifying than it sounds.
