Are you asking me about my personal lexicon of imaginary things?
Okay I will tell you about the nerkza; I.e that robot I have as my avatar.
It is a robot that shoots lightning and has a plasma globe head that is named "Nerkza". These robots are very advanced in tech, but despite that can't use it in any well thought out or clever way. They seem to always forget that they can use lightning for more purposes than zapping living life forms for example. The Nerkza are a result of a race of life forms who tried to ascend into immortality by uploading their mind to a bunch of cyborgs. However, their upload caused a very bad side-effect; it actually killed the life forms who "uploaded their mind" in their process meaning that they effectively near genocided themselves. Although obviously there are some pre-upload nerkza still around, but not many because it is actually a quite recent event, only happening 890 years ago. (millions in the galactic scale isn't that large if I am right.)
Another notable thing about post-upload nerkzas is that they are very solitary, and often pilot spaceships that have the ability to "squeeze" stars into oblivion alone. These spaceships are very large and easily detected, and take a couple weeks for the "squeeze" to finally cause the star to supernovae. While any space-faring empire can avert a nerkza attack (2 weeks is a good enough frame of time to board the nerkza ship and kill the pilot of the ship), non-space faring races are pretty screwed if one shows up in their star system.
