Time beast

A time beast was used by the Cabal of the Horned Beast and their masters to kill time sensitives throughout history. It was able to completely sever them from time, as though they never existed. (PROSE: The Severed Man, Echoes, Child of Time)

Honoré Lechasseur and Emily Blandish helped it escape by letting it devour the timeline of an unborn child. (PROSE: Echoes)
