Doppelgänger

Definition
Doppelgängers are a constant occurring phenomenon created by magic.

Origin
Doppelgänger's were created by the Goddess Odeyssia as a manifestation of her beliefs and faith that the 'soulmates' concept exists. She was so fascinated and envious of the love that humans - and species alike were able to experience that she conjured up a 'blessing' of two people being together forever, with the bounds of life and death not being an issue.

History
Since Odeyssia knew that she couldn't create a species that cheated death, she instead worked around this by having the same two people keep reincarnating so that their love would remain on forever. Originally the first few generations of Doppelgängers would keep the previous memories of their past lives in entirety but that didn't prove well as the overwhelming accumulation of lifetimes in memories; that weren't 'technically' yours would end with the Doppel's ending themselves prematurely before they had a chance to find their other half.

Odeyssia also never took into account that a Doppel may become immortal, thus never creating a fail safe for a situation like that. However after the 'widowers' line finally came to a halt on both sides this prompted Odeyssia to create a lesser replacement line called Shadow-Doppelgängers to keep the balance in nature that her creations tipped. This occurrence happens in all and every Doppelgänger line.

Gaia and Anaeus
This pair was the first ever line that Odeyssia created, and perhaps the most well known but not for being the first creation. This particular strand has suffered great tragedies and many supernatural scholars and alike have penned the lovers of this fate, 'the widowers'. Many believed that they are cursed instead of being blessed.

It is also the shortest line of them all.
