SCP Foundation

Hello, I have an idea here that I would like you guys to take a look at:

So, the SCP begins with a spear/ax/sword (I don't think this would matter, it just needs to be a weapon) with someone's conscious trapped within….. No don't click away, I know it sounds like the Roman armor, but I have a twist that hopefully works.

Anyways, the mind inside can communicate telepathically, and at first, claims that the only way for it to move on is to slay a king, or the last of five guys with the same name but different pronunciations, as it got trapped within for too much boasting.

But wait, there is more: The mind inside is actually not a human but of a god (Not the eldritch type). It's inside of the weapon due to provoking other gods of his pantheon enough to be sealed within as a punishment. However, the god did this intentionally so that it may survive the fall of its pantheon when its worshippers run out.

Now, there are two follow-ups that I have:
1. The Foundation thinks about it and designs a procedure to free the god so they can "employ" him as a last resort.
2. The god is a lying bastard and just another eldrich entity.

What do you guys think?

I think the emotional potential of him realising that his "punishment" is actually his friends saving him.

I get the idea of his friends entrusting him with their legacy as a pantheon; they saw how great of a god he is and entrapped him inside this weapon, but his self-reflection on the past lets him to conclude that it was actaully his arrogance. And the tears starts flowing when he realise what they actually did.

Also: why a weapon?
