"I am CLEARLY the only one doing work around here!"
Intensely loyal to Helvion, Gregan is a bit of a tough cookie to deal with for most of the pack. Long story short, he's got some abandonment issues, and having been picked up by Helvion, this lonely grey wolf feels like he needs to do everything he can to impress the pack leader. And it just so happens that he feels like he's just better than everyone, even though most members of GladeFire came into the pack due to the same reason.
At the very least he's a good shot at hunting.
