Sacrifice.
Celestia and Luna are all too familiar with the concept. It's a concept that has molded them, strengthened them... and in a few tragic cases, betrayed them.
When they are willing to give up everything to save those they hold most dear, what might be left could be just the thing that winds up destroying the sisters in the end.
Awesomely awesome collab partner of awesomeness is Denim_Blue, who I should mention is pretty damn awesome.
