The Blowt can refer to one of two things: either a mysterious force that possesses creatures, typically those who have died, and connects them to the Bheara, or the "race" of beings that has emerged from the Otherworld to besiege Quelmar during the Fantasial Freeze. In either interpretation, they are antagonistic and violent, and seek the destruction of all living things.
What We Have Learned
When X the Paladin used the Wand of the Spout to freeze the Ocean, the Blowt emerged soon after. Strange creatures they were; dragonflyfolk, whalefolk, mosquitofolk, and other humanoid creatures that had never walked the lands of Quelmar now slew citizens of southern Osugbo. They seemed mindless at first; the only readily available pieces of information were that the Blowt are connected to death/places of death, they are enlarged by whatever force is animating them, and they can be summoned by blowing on flutes carved from the bones of other Blowt.
It was not until several PCs journeyed into the Veil that the nature of the Blowt became more apparent. A skeletal monster named Thesaurus waits beyond the realm of death for creatures to become Blowted, a fascimile of life to carry out the orders of the Bheara.
We have also learned that living creatures can become Blowt themselves, which boosts their physical strength at the cost of their mind - they are cursed to follow orders despite their own nature, as the Kaiju Penguin Blowt indicate. Some PCs have taken on this curse, Ravel's army now contains Blowted soldiers, and other variations may exist.
At the end of Act I of the Freeze, the source of the Blowt's energy is located in Paraska Manor. Whatever entity exists there is ancient, evil, and perhaps not of this world - it warps the very fabric of reality to bend characters like Savile to its will.
The Blowt as a race have taken up residence in the city of Ravel, have taken over Tusgrer, and a hole in the Ocean ice that leads to the Otherworld lies between the two cities. It is the goal of the remaining cities of southern Osugbo to contain this scourge and help Quelmar get back to a place of peace.
