Vessels (Mosaica vespera vas) are artificial containment Mosaics.
.anatomy
Vessels are humanoid in appearance, resembling an average 12 year old, reaching a height of 150 cm. They have white metallic skin and silver hair, and their eyes are comprised of LED screens with embedded cameras, usually displaying only a white iris, turning magenta when occupied. Their faces, although capable of displaying the entire range of emotions, will often remain completely blank.
.behaviour
Vessels were created by Ultraviolet to capture and permanently contain Vespers, basing them off of Soma shells. They do this by enforcing arbitrary code into the Vesper’s own cells, which allows Vessels to use them as their own. Vessels have little personality, not by design, with small influences from the captured Vespers.
.abilities
Vessels can contain Vespers within themselves, each having the capacity to hold one. They can then use the stored Vesper’s Root Vector, and even mimic its stance and fighting style. This also means whatever tics the Vesper might’ve had will also show themselves in the Vessel. Attempts at brute-forcing the Vessels open will result in the Vesper dying, and the only way a Vesper can escape is by somehow creating a window in which it can retake control of its own cells. Escaping is always fatal for the Vessel.
.production
Vessels are entirely manufactured by Ultraviolet. Their fabrication process is extremely expensive and time-consuming, so only a limited number is produced at a time.
