Blood stalker : About it : An blood stalker usually lives in the forest, their homes look like spider cobwebs, at the daytime, most blood stalkers may live in a cave because they are sensitive to sun. at night, they watch every human's movement and at the perfect time (like when you're sleeping) they strike on you then bring you to their home. Attacks: They may bite, but sometimes there's a leader and gives them a guide, so their tasks can be protecting humans, or hurting humans.
