Elden Ring

It sounds like you missed half of the quest entirely like I did. There's a whole sub-plot with Blaidd and I believe an alternate ending for him.

edit: Also that armor isn't your real reward. Dark Moon Greatsword is and it's pretty sweet.
Yea after my stepson told me about it I realized I’d missed it. Looked it up and all of the various endings after beating the game. Over 200 hours in and still so much I missed, incredible.
