Here's a bit of background on Tiberious:
Tiberious lived with his aunt for most of his life. His parents died of a pox when he was young and she was the only one willing to take him in. A friend of his aunt's would tell Tiberious grand stories of adventure. This stoked Tiberious's desire to get out and explore. He knew that he could never rely on his strength and proficiency with a weapon, so Tiberious focused on his one great attribute - his mind. He has been studying magic for a while, but is not interested in learning slowly under a master. He has heard stories of scrolls filled with great magic down in Stonehell. It's all he can think about. There is so much knowledge just lying there, waiting for him.
Tiberious apprenticed as a winemaker when he was young. He was never really good at it, but he did learn to drink and have a great time. He is generous with his wealth, and his wineskin. Tiberous is outgoing and optimistic, but his impulsiveness can get him into trouble.
