Prince Glenn is the youngest prince in the Kingdom. Before he was adopted, he was the Schoolmaster's son (before, y'know, the plague got to that guy) and therefore learned from a young age to love knowledge and reading.
He hates swordfighting, and avoids it whenever possible. He enjoys hiding in the castle library for hours on end, absorbing all the knowledge-stuff he can read. He often falls asleep in there, too, and one of his older brothers go in to throw a blanket over him.
In his older years, he began sneaking out through the windows of the castle library to "explore" the world. There, he met B (#ship), and befriended the thief Laith. Darren is not impressed with his younger brother's escapes, but cannot do much to contain him.
