Background
Brevin is the last of a noble line that has lived in Erimos since before the breaking. The wealth and prestige had long ago left the family and the families past is but a faded memory. He is the youngest and last of 5 brothers.
He was born into a world where he was not expected to inherit anything and had to make his own way. His family life was hard and it made him hard. He made his mark as an adventurer at a young age.
Eventually his parents died, then his brothers and he saw himself inheriting the family home. He turned it into an Inn and eventually ran out his wealth. He sold it to the adventures but stayed on to run the Inn.
