The Seven Seraphs were possibly the creators of the Warminds/Rasputin. They were the ones who hid the Seraphim Vault and Bunker RAS-2 in plain sight on the Forgotten Shore. They are also related to the ACD/0 Feedback Fence, which were made with Warsat hull material. Their symbol is also found on the Pocket Infinity. It is unknown if they're also related to the ATS/8 Arachnid, seeing as it has the same naming style as the Feedback Fence and the Bunker
