Once a common mosquito, she was mutated when she drank blood from a powerful wizard turning her into a humanoid creature.
For a while she was content with just feeding on stray animals or travelers who wandered too close to her forest. However word of her existence begin to spread leading to hunters combing the forests in search of her as a prize to capture or kill. Eventually she decided she had had enough and began searching for a way to gain more power to protect her land and her life.
She soon discovers that the source of her abilities is the blood she drinks. Any blood she can consume, beyond what’s needed to sustain her, is stored in her sac which she is able to use to amplify her powers. Unfortunately the blood doesn’t last forever and like a drug addict she’s always craving the next hit to regain her power.
While she succeeded in driving off most of the human population looking to bag her as a trophy kill, now she has created another problem – most travelers now refuse to venture near her forest. This has lead to Ni’Del being forced to start hunting away from her grove to maintain enough blood to keep her strength at maximum.
