Amalgus is a prototype. The Lyricist, the powerful and eccentric Designer, decided to see if the communication grid between units could be networked to increase the efficiency of a group. A collection of older, obsolete units were repurposed and made to interlock over a lightweight frame, and redesigned to modularly rearrange their forms as needed. They are able to act as a single entity, or split into many separate entities.
Because of the additional power drain, the Lyricist discovered that the separate units could not be away from the mainframe for extended periods of time, so an emergency spacial-fold system was integrated to teleport units back to the mainframe before they lost power.
The design was strong, but considered to have too many inherent flaws to mass produce, the largest of which was it's confusion and frustration in regards to single entities. The prototype was released on it's own recognizance so it could be observed over time.
Now, the multi-entity known as Amalgus offers it's service to others to test it's own limits. It believes it is a remarkable feat of engineering and intends to prove it. It has difficulty understanding single-unit entities and considers itself superior to them. It is quite young and eager for experience.
Due to conflict with the ruling class of single-entities on it's home world, the Lyricist has sent Amalgus off into the blackness of the stars to explore and gather information. The Lyricist believes Amalgus' unique and adaptable configuration will lend itself toward finding solutions to many problems and surviving unforseen events.
