Here's my boy Oberon, or GrimmTale!Nightmare for my new AU! I thought it might be fun to make his theme green, since people usually use cyan or blue for Nightmare. His whole deal is decay.
He can choose to decay the things he touches--but can control it
Everywhere he walks, belladonna blooms.
He produces poisons, and they leak out of his eyes and mouth--and sometimes other people-- when he's particularly pissed.
His main role is to release the trapped souls of dead animals.
He wears a cloak of green raven feathers.
His messengers are green ravens, and he often takes the form of a luna moth.
Because of their association to him, both ravens and luna moths are considered bad luck, and are taken as omens of incoming death.
Killing either animal is a very quick way to get Oberon pissed. He does not kill quickly.
Oberon, in general, does not like mortals. If they respect nature, he tolerates them at best.
Oberon rules over the Fae Realm with Titania (Dream) in the GrimmTale AU.
Related seasons to him are Autumn and Winter.
