You seem rather confident that Entropy is not NMS-related. However based on the response you got, I am simply not convinced.
I found this symbol on the inner ring of a Boundary Failure:
Also, the lore of Boundary Failures ends with references to our own reality being a simulation.
Why would Entropy know to reference NMS and WT in its response? It seems a bit more than a coincidence to me.
Telamon having escaped into our reality would be quite consistent with NMS’s lore about Telamon, particularly in light of certain crashed ship lore.
(See my post that MadHatter linked to above. Seems he beat me to linking it in myself LOL.)
