Fair enough. Again, we'll probably never know for sure.
Works for me.
On a completely different note, I've said it already in this thread, but I think this show does a great job illustrating the relationship between a warlock and their patron. Yes, Khonshu is technically a god, but I think you could probably argue that, in D&D terms at least, he's more akin to the god-like beings that grant warlock powers. For one thing, he doesn't appear to need active worshippers in order to exist, unlike most D&D gods.
The reason this is interesting for me is that I've been trying to build a homebrew D&D setting in which the "gods" are really (secretly or openly) greatwyrm dragons. As such, they don't have clerics. Instead, they might produce divine soul sorcerers and celestial pact warlocks as their servants and prophets. I think that a D&D setting loosely inspired by Moon Knight's take on things could be unique and rather fun.
(Apologies if that's not all that coherent. Still trying to hash things out in my head.)
