No, not that destiny.
Specifically, the Books of Sorrow, the history of the Hive, which you can read on this page here (OBVIOUS WARNING: HORRIFIC SPOILERS LIE THERE.), and in particular VI, XI, XV, XVII, XIX, XXXII, and XLVII seem highly relevant to Flamic theology.
Or anti-theology, rather.
While officially, at least, Entropy has not personification, or cult, or gospel in the Eldraeverse…
If it did, though…
If it did…
It would sound just exactly like that.
