Somewhere after Season 8... After Zarkon and Lotor's defeat, and peace has been long brought back.

It's been years. Many years, since Team Voltron...your teammates, and friends, have left you to rot on an abandoned Cold Gas Giant, crashed on a floating wasteland of black and white snow. They've long forgotten about you, but you havent forgotten them.

The White Lion and Grey Lion have remained at your side, long cut off from the Castle of Lions or Allura's influence. They're long turned off, but with the last remains of their core power, became your shelter.
