How not to befriend a Dark Lord… or is it Lady?
Summary
Harriet and Tamelyn, two souls. More similar then they would first appear, now bound together in the aftermath of the chamber. What could happen?
Note
Haven’t published anything in months, despite having several dozen chapters of everything and anything written. Can’t seem to finish anything though, this one’s one of the longer ones so I figured I’d post it. Enjoy.
