Thanatos VII

Thanatos VII was the inhabited seventh planet in its star system.

In 2370, a plasma conduit was manufactured on this planet using a new interphasic fusion process, which was later installed on the USS Enterprise (NCC-1701-D) at Starbase 84. However, this new process had attracted interphasic organisms, which later infested the ship's crew and made the Enterprise's warp core malfunction.
