   Summary

   First, you traveled through the universe.

   You did not expect to be crossing the multiverse and meet the same skeletons you know. But that's the thing; they are all different.

   Deadly. Violent. Destructive. Feared. Hated.

   They are murderers.

   Whatever it takes, you will find your way back home.
