After JC Denton merges with Helios in 2052, defects in JC's nanite architecture result in an imperfect merge, unable to control the power of Helios and leading to turmoil between JC mind and Helios, one cannot complete with the other. After he reveals his ideology of equality for all to his brother Paul and Tracer Tong and before he can no longer maintain control, his allies transport him to Antarctica where he can seek peace and hide himself while waiting to find a solution, where Helios with JC's nanites erected a sanctuary around a VersaLife base for himself, a living technological building, infused with his psyche and only those with the same DNA of JC can access.
Afterwards, JC fell into a prolonged partial coma, leading to a struggle with Helios and dividing its power in five part called Helios processing module, four describing an echo of an important event of JC memories and three protected by grays. In 2072, Alex Denton comes in the JC Denton's Sanctuary with the perfect nanite architecture in order to wake up JC and allowing his merged with Helios. Eventually, the JC Denton's Sanctuary was probably abandoned after JC Denton and Helios were one.
