Factorum Malleus

The Factorum Malleus (Common: Creator Hammer) was a weapon created with the intention of killing the gods created during the Age of Arcanum by Aeorian mages. The exact nature of the Factorum Malleus is unknown, but the "hammer" in its name is metaphorical.

History
On the Apogee Solstice in the late Age of Arcanum, the day before The Calamity began, some in Avalir knew that Aeor intended to test a weapon in a "dry run" attack on Lathras, a smaller flying city, before using the project elsewhere. The exact project involved in this test is not known, and Aeor had multiple ongoing projects, but it is possibly the Factorum Malleus.

Devexian, an Aeormaton living in Aeor, described the Factorum Malleus as a "means of protecting Aeor from the divine destruction" occurring during The Calamity; he assumed that the project directly caused Aeor's destruction by the gods, who deemed it too dangerous. Aeor's research into killing gods and that research's relationship to the city's destruction was well-known to people living later in The Calamity and in the Post-Divergence and makes up most of what is remembered about Aeor.

In 836 PD, during Campaign 2, Caleb Widogast found notes on the project in the Genesis Ward describing it as needing more time but finding its early results "satisfactory".

Trivia

 * Factorum is a form of the Latin factor ("maker", "doer", "one who does or makes something"). Malleus is Latin for "hammer".
 * The Factorum Malleus Project has a similar name to the Malleus Keys, a project in 843 PD aiming to release Predathos to destroy the gods.
 * The name "Creator Hammer" is similar to that of the Godhammer Bomb in Pillars of Eternity. Matthew Mercer voiced Edér Teylecg, a worshiper of the god killed by the Godhammer.
