A new character. He's from an EFH spin-off (yet another) so he will not be part of the main story, but he is technically from the same universe. (which doesn't really mean much! XD)
He is a rogue Annarretyn, there for has very little power.
Rogues can appear on their own from the left overs the first and second generation where made from or they can sometimes be the result of a failed experiment. Failed experiments are frown back into the soul stream to purify the souls used. On occasion, the opposite can happen, where the energy and mass from the experiment is enough to gather it's own souls there-for becoming a rogue that way. They are never as powerful as the made Annarretyn, weaker even that the 5th generation making them as close to mortals as the Annarretyn can get. They still retain some powers but are not very proficient with them. they also have to find ways to sustain them selves.
The soul stream dumped Eorohan into a vampires nest where he learnt some magic. He also killed many of them and stole their power to replenish his own in the early years of his existence. This has given his some vampire characteristics. Being full of souls, he has a grasp of necromancy. One of his main abilities is to infest a body. However this is not always in a malicious intent. He sometimes inhabits the body along side it's original host, only taking over when he needs to. This allows him to have a solid form as he lacks the power to generate his own. If the bodies own was to let him run the body, he can alter it's external appearance to others, effectively creating a mask of his own chosen appearance concealing the real body. He can also use his powers whilst inside a body.
He does not require but finds the benefits of having one very appealing.
I have some quick doodles of him on my tumblr if you are interested.
