Lethologica (Voltron)

The team is struck by a spell from the witch Haggar that makes them unable to rememeber what happened during that mission. They think that they discovered a plot of Hargrids and are now determined to find out it is.
But there's something deeper going on. Theres something missing and everyone can feel it. Something more important than whatever plot Hagrid has. But how can they find it if they don't even know they've lost it.

Cover art is not mine (I'm not sure who's it is, I found it on google. If you knows whos it is let me know).
I do not own Voltron, that belongs to DreamWorks.
