This will prob be like the regis where the human enemies come later while vehicles and robots come first

"Ruins" of another faction. There is only 1 structure in the Exo Era that can be considered "Ruins". The Wisteryn Abandoned Dig Site. However the fact that they got a mech from a wisteryn blueprint is weird, why would the wisteryn make a mech? Well I got a small theory and just look at the Wisteryn flatback and then look at the jump pack. The flatback's legs were probably used for climbing luse structures/mountains and probably the jump pack of this Cyclops was made for luse structures/mountains. Also very "compact", just look at the Wisteryn Shield, it's pretty compact for being able to have an energy shield.

I conclude that this blueprint was found in the Wisteryn Abandoned Dig Site
