I always do a backstory for my characters, but I have had difficulty coming up with one for this character.
His name is Lerondil, and he is the middle-aged of three brothers. His mother died during the birth of his most recent brother. His father was a former mage and is now a government official.
From there I don't know where to go. What conflicts occured during his lifetime? What did he do for a living? Why did he flee Alinor, and what was he doing in Skyrim?
His disposition is most likely going to be good/neutral and he will prefer to stay out of the civil war.
