Aegis

The Aegis are the grand armors of the Order of Mars. Forged from Aegirium, a rare and odd metal, the Aegis is a "suit of armor" as its called, although it is much more akin to a mech than simple armor. These armors are the ace of the Order of Mars, crucial in their battles both planetside and in the void. The metal itself being hard to work with limits the accessibility of the Aegis- requiring particularly skilled Metalworkers in order to process it. Added to that is the rarity of the metal, which is usually only found in large quantities in certain systems.
The special properties of the armor in tandem with technological developments enable extensive interfacing between the pilot and the armor. This serves to organize interunit coordination, as well as to monitor and concentrate the user's experience.
