So we'll just go through some basic stuff about the ship and then I'll say my opinion on it...

Characters: Edric Blight & Emira Blight
Canonical?: Fanon
Relationship status: Twin siblings, Brother & Sister
Other ship names: Blight Twins, Ed and Em

So what do I think?:
-100/10
They are SIBLINGS, to be more specific, TWINS!!!

Thanks for reading and see you in the next chapter, byyeeeee!!!
