Risa was used as a guinea pig most of her tiny little life for the sake of experiments, at the age of 2 she was taken from her tribe as she was playing with some branches by herself. The people that took her were a rather peculiar group of dark mages who call themselves "The Ravens".
She was brought across the waters to a place called Crossroad Mire where The Ravens had vested their base of operations, here they experimented on people of all ages.

Risa was one of the chosen few to have demon blood forced into their body, each person a different type of demon blood (The blood forced upon Risa was that of a demon wolf). Most people died from this experience since demon blood is much stronger than that of a human, it would force people to go berserk, have them turn into a monster completely or having their heart or mind completely destroyed. If that were the case, The Ravens would take their captives lives.
Surviving this would make the person a valid subject for the next step in The Ravens their plans, they would start breaking the mind of the survivor(s) by use of magic such as hypnosis or dark magic used for torture. The Ravens were looking to make an army of puppet half demons and/or monsters to strengthen their numbers.

Learning of their plan a group of people send by a large guild from Alliria attacked The Ravens, destroying their base and freeing the survivors. The Ravens however were not defeated, when they were attacked they simply vanished in the fog surrounding the lands of Crossroad Mire, though now little in numbers all they had to do was... Start over.

Risa now roams the lands around Alliria and sometimes the streets within the city surviving on what little game she can catch herself.
