Owlites were the original creators of elemental weapons, armors, and shields, right?
So how do Gremlins deal elemental damage and use elemental weapons?
Before the spookats completely DESTROYED the owlites were the owlites and gremlins in an alliance?
Is that why gremlins are weak of shadow (afraid)
because it could possibly end them one day?
I DON'T EVEN KNOW ANYMORE
Slow down there. Just because Owlites created elemental weapons and gear doesn't mean they're the only ones who could've/can. The Gremlins probably developed their own sources of elemental damage and defense, or learned from the Owlites themselves.
The rest of your post seems very um... speculative. ._.
