this is ursa !! they are the lovechild of aeon and stygian
necrolumes do not develop a physical sex until they are 10-12 years old, so ursa is genderless!
they have the ability to produce stars from the drool in their mouth, which forms bubbles, thus creating stars when popped (ursa is the only known necrolume to be able to do this, making them extremely prone to being kidnapped)
