Deimids

Mortal understanding of ordinary celestials is limited. Recorded interactions with them are few and brief; they are not often interested in staying long enough to be interviewed. It's not known how they arrive into existence, or how their society works, should they even have one. They are known to come in a number of types, each seeming to have its own function, and they always serve a specific deity or deities.
But sometimes their deity dies.
It is theorized that however celestials come into existence must be innately tied to their era or their particular deity, or else deimids would not exist. When eras transition with the genesis of a new pantheon, celestials do not transition with them. Instead, they wilt. A part of them dies with their deity and all that's left behind is a husk of what they once were; a being with all the strength of a celestial who knows only dread and anguish. They are by far the greatest threat to a newly formed pantheon, which is often small in number and new to their abilities. Their only goal appears to be the destruction of those who destroyed their pantheon.
It is not known how many, if any, deimids still exist in the modern age. Most are believed to have been eliminated in the first century of the era, but some have suggested that the recent appearance of sea-crawlers in the Astrum Sea may be a related phenomenon. Some have suggested that sea-crawlers may in fact be deimids in a very advanced stage of their decay that have somehow found their way onto the mortal plane, and attack indiscriminately because they are no longer able to differentiate between mortal and divine.

Basic Information

Anatomy

Deimids sometimes resemble the forms they had as celestials, be it a lantern archon or an angel, but are often described as hollow or decayed versions of what they were before.
