Contains SPOILERS for The Sword of Summer. Read at your own risk.
Halfborn Gunderson is a viking warrior who's is probably literally insane. He charges into battle and slaughters people left and right. He continues to fight even when he's injured and even nearly died in the end of the book due to his injuries. Oh, he also has 1200 years of experience fighting. It's casual.
Tyson is a Cyclops son of Poseidon who is the general of the Cyclops army. He's not very smart, but he's very useful in battle and is good with his hands. He can also grow up to 30 feet tall. Still casual.
