Horizon of Strange Stars: Cosmic Dump

So, I've started drawing the designs for the Horizon Gate 5 Servants and MAN am I excited for the cast. It hasn't been 100% figured out (I kind of want to add a few more Servants that fit the prehistoric/ancient/post-apocalyptic Horizon Gate but I can't think of many) but once I got the idea of Adam's profile, I decided he needed to be in this chapter. It just fits so well. Initially, he was meant to be a Pseudo-Servant using Gun God as a vessel (hehe, last man sharing a body with the first man), but idk. Part of me thinks Adam stands well enough on his own. Part of me wanted to do some silly word play and make hima Pseudo of Ado Edem, but that would require changing his design which I couldn't let go of. Pseudo Servant Edem is still a possibility with a somewhat ironic identity.

Ah whatever, here's Adam (Ruler), he acts like something of a guide for the Chaldeans throughout this Horizon Gate; something like a boomer dad trying to teach his kids camping is the image in my mind. Although, he isn't the MAIN companion for this chapter.

Can anyone guess who
