Biography
Not much is known about Erui, however they do seem to have some connection to Elke as they tried to protect her from Manaia. They also offered protection to Ketifa and tried to persuade her to go with them, the attempt ultimately failing. Soon after, Erui was killed by one of Ketifa's stone golems. They may yet still be alive somehow, as Neriss claimed they later killed her. The next time Erui appeared was in the Mandragoda Labs, where they nearly killed Tiberius and Maiwen for the sake of some fun.

According to Hirlo, they are a member of the Seven.
