The Feral Continent
Formless, timeless, and not even slightly understood, the Screamers exist as formless, seemingly infinite spirits under the command of their god, Parash.
Around since the beginning, it was originally considered quite a divine blessing to be chosen to carry a Screamer as its host, allowing it to take up your body and take control over it from time to time, but it never lasted.
Screamers possess an incredibly destructive power, a pure chaotic evil that tears apart their host if they're too weak to sustain it. This makes even the weakest Screamers dangerous, as the rage their host enters when they begin to fall apart can destroy buildings and raze villages.
They have a direct connection to Parash, god of corruption and betrayal, and they speak and act upon his will and ambitions.
Unmatched in their killing potential and their destructive power by any force known to those on the continent, and able to possess any body (even animal, even dead) strong enough to hold them, the Screamers are the purest form of a Feral gods power to ever exist, even above Ba'Shatas Twilight Princess.
The more powerful the host, the more powerful the Screamer that can possess them.
While weaker Screamers are mindless monsters, unable to contain their own power, the stronger Screamers are cunning, clever, and a purer evil than their weaker counterparts can even imagine, capable of devastating magic and power.
But the strongest Screamers, known only in legend as the Perfects, have never been embodied.
The party have so far encountered a few of the Perfects:
Bulchdel, who possessed the body of Maxwell (Samson of Loge 12's younger brother) through unknown means, slaughtered Maxwells companions and hunted down Lodge 77.
Although Maxwells body was slain, Balchder escaped, but not before leaving an ominious threat to Boris, that Boris is now his prey.
Paragon Lucille also remarked that she had encountered another Perfect prior, known as Ira, down in the Wastes. The party later encountered Ira personally, and she slew Boris and Samson
The party encountered Bramare at the town of Gritspire, where she was using her twisted powers of compulsion to force the townspeople into building a temple dedicated to her to raise her own power, hoping to use her new power to increase her influence and bring the continent under her control.
And finally, the party encountered Preguiza, in the old asylum at Hearthfield, where he took over the body of Paragon Bafdor. They challenged him when he emerged in the North, and Eleanor managed to slay him with the dagger of soulglass, absorbing his power.
The party also discovered, from Gisei, that the Perfects were originally called the Omologies, and were ancient.
