This story is a sequel to Sunset's Adventure in Skyrim

Life on Veldin, a planet in a remote corner of the Solana Galaxy, is becoming somewhat boring for Ratchet. Fortunately he's got two younger sisters that bring some excitement to his life, despite all three of them being different species. One of his sisters is a unicorn named Starlight Glimmer, while the other is a Cazar named Sunset Shimmer.

All Ratchet knows is that the three of them all arrived at the Veldin Orphanage together. One thing they can all agree on, however, is that they need to leave their home behind so that they can truly find their place in the galaxy.

Everyone knows that Sombra, the Tyrant of the Crystal Empire, got blown apart by the power of the Crystal Heart, but has yet to resurface. What everyone doesn't know is that he got blown across the sea of worlds, leaving fair Equestria behind. The problem is that when he awakens he has no idea who he is or where he ended up.

Will Sombra be able to let go of the past, and his hatred, in order to save a world he's never seen before? Or will the citizens of Tamriel have another villain to worry about?

Sunset Shimmer almost succeeded in taking over Canterlot High, stopped the Sirens from taking over her new home, and managed to prevent the destruction of two worlds. She feels that she deserves a break and decides to return to Equestria during her summer break. Unfortunately, when she enters the portal she appears in a land that is different from the worlds she's already been to. Now she has to save this world before she can even focus on returning home.

Unfortunately, she's not the only Equestrian that's appeared in this new world, as one of Equestria's most dangerous villains is loose to do whatever he pleases. How will she cope with having to save this new world from Tirek?
