One of the 6 classifications of Daeva (abominations) used by the Vigil. These are the Ehoshim that were on Aaru when it shattered. They have been fragmented, existing on multiple worlds of the Heptarchy at the same time. These being make the Vigil uncomfortable, and they are very careful about interacting with Dimmu, often going out of their way to avoid encountering them. Though the Epheirim can make it difficult. The Vigil have tried to imprison Dimmu before but it never works since as soon as they are put into a stasis cell they die. Some theorise that it might be because they are still linked in someways to their other selves and the stasis cell breaks that connection, but no-one really knows for sure.
