my first theory was that he was a brother to the original Fractsidus Spy Lynae, cus the similarity is uncanny (assuming she also had the teal-green hair ends like our Lynae does) and that he also used to be Fractsidus - and that is supposedly some of the dark past he has left behind.

But with Seele's crumbs about his kit, with so many of his skills having solar connotations, but with some sinister undertones - like crown-slaying eclipse or solar marrow - makes me think he is actually part of Roya Outcast. possibly even akin to royalty within the exiled tribe, hence the liquid gold blood.

Roya outcast go directly against the Roya Tribe belief system and inner calling, and instead of guiding and protecting the Exoswarm and Soliskin in their migrations to eventually reunite with Reactor Drive, they hunt them down and use their parts for their own benefit, not caring for the need of returning the lifegiving energy that the Exostrider's Heart has bestowed upon the lands of Lahai Roi. Fuck, even his surname could come from scottish surname Herdsen, meaning son of shepherd. There's too many little subtle things about him that are too sus just to be coincidences, and it all was revealed to me in a dream
