Abersyn symbiote

Abersyn symbiotes were a non-sentient species which feed on the brain stem of sentient species. They had to be fed into a plasma furnace in order to kept them in a quiescent state, though a regular exposure to a plasma vent has been proven to have the same effect on them. They were known for being responsible for the death of many historical empires, therefore having an specimen was banned by Imperial decree.

History
During her time as doctoral student in the University of Bar'leth, Aphra was studying and exploring the planet of Boothi XII looking for an incredible discovery (supposedly a nest of Abersyn symbiotes).

After finding nothing on Boothi XII, Toob-Nix, Aphra's doctoral supervisor, showed her a full nest of Abersyn symbiotes on his personal chamber, telling her why he hates her so much and that he's not ever going to give her his approval to get the doctorate.

As revenge, Aphra stole the hole nest with the help of Sana Starros and make it appeared as if she had finally found the Abersyn symbiotes on Boothi XII. As part of the Imperial protocol, the symbiotes were disintegrated right away, possibly terminating with the last specimens of the species.
