Narus acquired ex CIA agent Maya long before, all first world nations were liquidated, coalating to form it. She worked for a while like the rest of the executives, and found that the agency, was dissolved, and most of the agents back then, retired and formed a sudidary of Narus, under Netajis guidance, called ICA. There were many rebels mutants enemies that Narus had, ICA was built in response to that, which was the crux of the military wing of Narus.
Maya was later given a offer to join ICA, only as a consultant with high pay perks bonuses. But she knew nothing about X, and that he was behind, everything that had happened all her life. Later she realized like all innocent people in the world, she too must fight X, in the form of ICA for her.
