Preserver obelisk

The Preserver obelisk was a type of technology that was built by the Preserver species..

They were constructed from a phase transition compound which only existed in nature at the hearts of white dwarf stars.

By 2370, 119 obelisks had been discovered which ranged from 2 billion years old to just 6 years old. In 2375, one such obelisk was present within the First Federation asteroid base where it was directed an asteroid to destroy the facility to prevent it from falling into the hands of James Tiberius Kirk. A second much larger obelisk was present in the Mirror Universe over the counterpart Halkan which was part of a plan to channel great energies into the Mirror Universe and destroy it but this was thwarted by the crew of the USS Enterprise.
