Sedi Fisk was considered one of the original settlers of Tatooine. Of a species and sex unknown, Fisk lived in a manor in Tatooine desert until 1 BBY. He was known by other locals.
At some point, Fisk decided to abandon his manor for unknown reasons, without telling anybody. Eventually, it was overrun with womp rats. On 1 ABY, this was discovered by a team of Rebel agents looking for Adar Tallon.
