Ileman-Loch's 5th generation Light Strike FOIL Aetarius was produced in the same time period the previously posted Ileman-Loch Auaris-SOMR (Special Operations Multi Role) combat FOIL. They both share some slight cosmetic similarities and are both high mobility machines designed for combat operations requiring speed and precision. Beyond that though the Aetarius is more of a workhorse front line machine. Slightly heavier on armor than the Auaris-SOMR Aetarius is quite capable of taking punishment. Aetarius is somewhat of a beefed up high speed infantry FOIL at heart though quite capable with bladed weapons.
The example pictured here is a Polemon machine in service of the Free SOL allied forces that stand in the face of the Siege of the Black Son. It sports pattern breaker on the covering on the limbs and tonal variation breaker on the blue gray body panels. It's carrying an assault stein shettier rifle manufactured by Dies. It's highly likely the FOIL also sports a good deal of Dies parts as well.
The Latin text under the FOIL is actually on the FOIL, placed there by the Pilot and Faedai, it say's, "Reality is an illusion. Awaken from the dream." I also should note the name Aetarius was coined by

as a play of Aquarius. He thought the FOIL's legs had a bell bottom vibe so the name kinda spawned from there

Also will note there are GenoPeng/Vulne FOIL collabs coming soon
