The spokesman of three Takret who warn Enterprise of an approaching neutronic storm and take shelter with the crew, concealing that they are deserters hunted by their own militia.
Tagrim is a Takret who appears in the Enterprise episode The Catwalk. With his companions Renth and Guri he hails Enterprise to warn of a vast neutronic wavefront and asks for refuge.
The three join the crew in the cramped maintenance shaft along a warp nacelle, the only shielded part of the ship. Tagrim presents his party as stranded travellers, but their evasions make Jonathan Archer and T'Pol uneasy.
When Takret Militia soldiers board the ship, immune to the radiation, Tagrim admits that he and his friends deserted from that corrupt force. Archer bluffs the boarders into leaving by threatening to destroy Enterprise, and the fugitives are able to go on their way.
