A being from another dimension that has no particular shape. It travels through portals to our universe, in order to transfer energy – souls – to its world. It consists of an unknown element, that allows it to create flesh and take human form. It reaps the soul of a mortal when its ties with the body are loose. It is, as humans call it, Death. More details: All Niruvei lived in the other dimension and visited our universe only to reap. Some thousand years ago, the energy equilibrium between their world and ours was distorted, causing some of them to stay permanently in Earth. They still carry souls to the Other Side, but they are forced to come back. Shapeshifting has limitations to their colors and sex. The energy they take from every visit in their realm is more than enough to sustain their body. Niruvei never grow old and never die of natural causes.
