Lotor has given Voltron anything they wanted. For months, he's allowed himself to be locked away as a prisoner and treated less than everyone else in the castle. Finally, after many successful missions using his intel, he's finally convinced Voltron to take his suggestion on their next target.
Alwain.
With thousands of resources, it's clear why it's considered valuable- and why its security measures are through the roof. If taken back, it would be a MASSIVE victory for the Collalition. However, after some digging, Pidge comes across a vital piece of information that Lotor "forgot" to tell them. Years ago, after the solar system's thousand-year rebellion had been forced to an end by Galra forces, Lotor was dragged back into Zarkon's plans when he and the Crown Princess were forced into marriage to secure control. While neither is originally thrilled about the arrangement, they end up falling in love. Sadly, Lotor was banished to the end of the galaxy. Any attempt to contact her will mean the end of his lover's home, people, and her life. With no other choice, he's forced to wait. Now, he finally has the opportunity to rescue her from Galra oppression, and nothing is going to stop him.
I don't own Voltron or the characters, just the plot of this fanfic. It's implied that reader has a lifespan similar to Lotor's. This is not meant to fit perfectly into the canon series, so just think of it as a canon divergence, or an ALTERNATE REALITY... I'll go in a corner now...
