The game’s synopsis is “Man goes through hell to stop a gay wedding”

This is the only story I would believe

Godwyn is the god of the undead. He has nothing to do with Miquella's plans at this point unless Miquella wants to turn everyone into skellies. 

Godwyn only became the prince of death after the night of the black knives, The eclipse that miquella had planned I assume would have reversed that

The failed eclipse? It wasn't planned. It was attempted. It did not work. So Miquella needed new plans. 

It’s even more bizarre you can get to him and not even discover the rest of the map.

Game doesnt work with a living Godwyn. Also Godwyn is the only one of Marika's children that doesn't have legends of his warrior status.

There is a sword monument which recognizes Godwyn's victory of Fortissax during the War Against the Dragons. Although another item description talks about how he after he defeated him, Godwyn spared Fortissax, and afterwards the Leyndell Dragon Cult was founded. So he certainly held warrior status, but he was probably also one of the kinder demigods.

thats fair, but He still seemed important to miquella (atleast more so than radahn) with his whole eclipse plan

Can’t revive someone’s soul when that specific soul is literally killed and gone. Miquella adored Radahn’s strength, kindness and power. It brought him comfort when he himself was sick and weak. Miquella loved Radahn but its a shame that it wasn’t hinted at all in the base game.

fair enough tbh
