This is Amithisia's alternate account of all things Eclipse. The books on this account contain fanfics and stories that belonged to the Earth that knew her as Vader's Shadow. If it is part of that world's "canon" (which is unlikely); it will be labeled as such.
Basically this is just going to have a lot of alternate stories involving Darth Vader's apprentice and the differing degrees some people may view her-an activist or passive person; a full Sith or more of a dark Grey; someone who loves killing or someone who kills as a necessary evil. All that will remain the same over these stories is Eclipse's loyalty to Vader and her origin from carbonite along with where and when she was supposed to die (which doesn't happen all the time because fanfics)-even her name (not title or second name taken) will change.

Follow the main account @Amithisia and read her "canon" story and origin (beyond the carbonite) there.
