Warframe prototypes, or as close as possible from the image Ballas had in mind while designing them are the prime warframes. The first one is Excalibur Prime.

Ballas seemed to have a thing for shattering the minds of traitors (as seen in Ordis' fragments) and decided to turn Umbra into a warframe, but not any warframe. It seems to imply he used a special or unique method for his transformation in order to preserve his memory, or at least the particular memory of him killing his son, the result being an unique warframe, resembling the Excalibur model but slightly different. In the end, Umbra became enraged, was able to move without transference and desired to destroy Ballas. During the quest, the synthetized umbra parts have traces of minerals from Lua, and later, when entering the orokin lab where you find the vitruvian, Ordis says a line that seems to imply Umbra was contained in that lab, and awakened or was set free after the moon was pulled from the void during The Second Dream. It is possible that Ballas decided to imprison him there, as he considered him a "mistake" and was unable to use him.
