The Dark Secrets of the Vatican
Swallowing a mouthful of saliva, Lisandra read about the records.
Angels with an unbalanced nature could not move or fight as they were in constant agony. Their minds were being bombarded by dark thoughts while their body refused to transform, causing a split between body and soul.
This split would often kill the angel within the span of a month depending on their will power. Those with weak will power would transform into a new race within a single day. Their bodies mangled to the point it was barely recognisable.
They were titled Screaming Terrors because they grew several additional mouths so that their agony could be heard.
Most of the Screamers shared the similar traits of a mangled body that had multiple mouths, wings that grew wherever there was room, hollowed eyes that would flow with black substance should any living being be near their vicinity. They would show a great deal of hostility to all forms of life.
