The planet never really recovered, and was converted to a penal colony by the Kal`Shebbol government in the days of the Old Republic. For many years, convicts labored in camps to rebuild the infrastructure sufficiently to allow resettlement. However, some years before the work had progressed to the point where extensive resettlement was a viable option, the young Empire swept into the Kathol Sector and abandoned the colony, stranding the convicts there. Many of the convicts died in the ensuing riots, and still more died by starvation and exposure before the new self-appointed leaders of the community could create some semblance of order and lay down plans for sufficiency.
Over the years, the colony has managed to establish a self-subsistent society. A lot of trade takes place between Timbra Ott and the rest of Kathol Sector, not all of it entirely legal. Smugglers can do their business openly here, though the local law enforcement agency still takes steps to ensure the safety of Timbran citizens.
