Species: Oniron (Dreamcatcher Dragon)
Description: Oniroi are creatures that prefer the world of dreams and rarely cross into the physical world. They are considered guardians agains the nightmareish powers of the Barathroi. Oniroi are immortals and usually choose a lineage to protect. Each member of the family chooses a stone or a trinket that represents their inner peace and adds it to the ones already attached to the Oniron's tail.
