Now introducing the shadow alicorn that give Blade his powers:
Void, the shadow Alicorn of death, and one part of the element of Justice:
In the FoE spin-off au (and even the Rainbow01 universe), Void is sorta the embodiment of death, darkness (as long as no one pissed him off) and justice, in other words, the grim reaper of the underworld. Heck, some say he’s kinda like Princess Luna in a way…(hmm, I wonder why looks at Nightmare Moon, King Sombra, Pony of Shadows note, Void stated he’s not related to him* Lord Terik…) Void then got captured by a cult (Alicorn Co), who’s wanted immortally and rule the wasteland. A couple of moments later, Void was transported inside of Blade, and after talking to each other, both Void and Blade look out for each other (mostly void tho..), leading up to Void sometimes being a mentor for the now turned alicorn.
Void’s powers vary sometimes, and often get used by Blade in the au of FoE. If Void ever gets angry, he will go on a rampage and do whatever it takes to protect his host.
In the Rainbow01 au, Void is not inside of Blade body, instead he’s more of a communicator and will be at his side when Blade needs his help. his mind is connected with Blade, marking him as a host. Both Blade and Void can either communicate telepathically or the shadow alicorn can just materialize himself next to Blade if he wants to.
