   Summary

   Adelaide wakes in an all too familiar world, and she is not happy about it, but a chance meeting with Horus lupercal seems to bring her closer to her goal; helping her younger siblings escape the grim darkness of the far future. Unfortunately, chaos is not going to let her mission become easier, fortunately, she can't seem to take three steps without stumbling into a new larger than life ally.

   Basically I just wrote what I wanted to write. Sue me.
