Voh was a Bimm male who held the position of seneschal at Sanctuary Mount. Sanctuary Mount was a Jedi Order outpost located on the planet of Kwenn. Despite not being a Jedi himself, Voh dedicated a significant portion of his existence to maintaining the outpost, encountering numerous Jedi Masters belonging to the Jedi High Council.
On one occasion, Voh encountered and secretly conspired with Palpatine, a senator from Naboo. Voh provided the senator with access to and authority over Jedi writings housed within the outpost, including those containing prohibited knowledge. In exchange, he secured the Republic's continued investment and interest in Kwenn. Voh later breached this agreement by choosing to sell off the texts Palpatine demanded be destroyed, considering them valuable historical records worthy of preservation, remaining oblivious to Palpatine's secret identity as a Sith Lord.
During the Council's deliberation regarding the potential shutdown of the Kwenn outpost, Master Eeth Koth mentioned the impact it would have on Voh. However, Master Adi Gallia pointed out that Voh was nearing the point where he could no longer effectively fulfill his responsibilities, and finding a replacement would be challenging. Nevertheless, the Masters agreed that Voh deserved to be informed in person, leading Master Mace Windu to determine that the entire Council should visit Kwenn.
