Vaankara
The Vaankara was a Vulcan starship that was in service with the Vulcan High Command in the mid-22nd century.

This ship entered the Delphic Expanse in December 2152, searching for the Seleya. () Less than two days later, the Vulcan High Command received a distress call. Six hours after that, they received a transmission of the crew killing each other bare-handed. An hour later, the starship was destroyed; there was no evidence of a malfunction or an attack, leading the High Command to suspect that it self-destructed. ()

It was later discovered the crew had been driven insane by exposure to trellium-D, which had degraded their neural pathways. This served as a precedent for the crew of the Seleya. ()
