In Alia's words.
"The Mark Five External Universal Interface Artificial Muscle Powered Suit MK6, labeled the Lily, this is the perfected version of the environmental suit with virtually all flaws removed from it and the systems present, including an enhanced power relay system on the back, making the power generation and distribution far more efficient than I had ever been able to make it, this comes with a change to the generator as a whole, many of these changes come with a young woman by the name Annie, she is a rather unorthodox engineer, which leads to these changes, most of which I would not have come to on my own, along with a style change, adding a new feel to everything, lastly, she appears to have chosen a yellow crystal for her reactor, strangely befitting of her. As of this time, any and all advancements to this suit have been halted, as a unanimous agreement across the staff have come up, we can not make anymore changes"

So it is, the suit ends, and a style change is made~
