‘Dark Ata’ as Ata has come to start calling it, is a strange creation by the Monitor to replace Ata in his grand plan after she failed to be affected by The Great Schism's corruption like all of her siblings. 

 Dark Ata appears to have many of its frame’s personalities; being feisty, self confident, needing constant validation, and headstrong. However it is without anything the Monitor may see as a flaw such as her attachments to her creations and humanity. It also is made up of a strange non-newtonian-like material that The Monitor claims only he can make and use. 

 When deployed, Dark Ata manifests itself from its puddle of mass and begins its duty. Dark Ata is nigh unkillable as all attempts to destroy it merely leave it dispersed and will reform within seconds. If hit with a hard enough attack it may take longer and repeated breaks may overload its factor and cause its healing to take far longer. In combat, unlike its frame, Dark Ata doesn’t rely on shaperpaint or weaponry, rather its own body. Due to being essentially liquid metal, Dark Ata can form pieces of its body into any weapon it wants. From mimicking Ata’s tendrils, making its arms into swords, to creating a swarm of needles. It’s able to control all pieces of itself even if they’re attached to its greater body or not. This allows Dark Ata to be as versatile as it needs to be and the Monitor believes it’s his best creation, much to the Emissary’s jealous ire. 

 Dark Ata often is referred to by others as female, but it technically does not have a gender due to simply being a living liquid substance. However this has caused errors within its mind, as The Monitor manually removed all things of Ata that he believed may cause Dark Ata to be less than perfectly loyal. Yet ironically this has caused Dark Ata to become unstable as holes in her mind has caused many errors and gaps to form. These areas are slowly being filled every time she fights Ata or is sent to set another Worldshaper straight. It’s only a matter of time until something within Dark Ata changes irreparably.

 Along with this, due to Dark Ata being modeled after Ata and whatever it’s made up of, it technically became a Worldshaper. Quickly it’d involuntarily take the traits of stillness, artblock, malaise, and stagnation. Not in the way of Vias in the way of willing avoidance, rather the loss of one’s muse. The desire to make is there, but the mind’s eye is not. It’d also claim that of freedom and rebellion, despite being immensely loyal to the Monitor. What this could mean is cause for concern on both sides.
