Sokketh was a Vulcan ambassador on Earth in the early 25th century. In 2409, while stationed to Spacedock 1, he was killed and replaced by an Undine agent.

Sokketh's replacement then attempted to go to P'Jem aboard a Federation starship, but the ship's crew discovered the agent's true identity and were able to persue and capture it. (STO video game: Star Trek Online)
