E Looks like the new Vegas in-game courier's satchel. Vault boy on it too. No sleep for the courier maybe. Could be Ulysses prequal and a tie-in with how the Hecate came from his tribe and thinks she is a goddess. What a coincidence her civilization's name is Ouroboros. Her religion is about "life/death/recreation"

I think it is Fallout something and has to do with the Hecate and her cult tribe thing. Look up Ouroboros on the Vault wiki. Religious stuff would fit in. A user posted a link to the page in the first thread, that made me realize this.
