Alright:
So starting off, you seem to have a general idea of what you want to write about in your article, this is a good thing and can keep the idea and article consistent through the narrative.
However, what is the sword trying to accomplish? What are "The Corrupted Gods"? And why is the sword trying to kill them? You should at least give some idea in the article about how these are related.
Also as a general note, stating that the sword can cut through anything, and that the composition is unknown, is a quick way to get your article down voted very quickly, as that can be seen as low effort writing. Might I suggest that the sword can only cut through material that the wielder see's as something related to "The Corrupt Gods", which can be further influenced by the sword itself? As for the composition, why not have it simply as durable steel that regrows when a new wielder takes up the sword?
To be honest, articles that revolve around relatively simple items such as what you've described have to have a decent story behind them to make them stick around and stick out on the site these days, and while its not impossible, it can be hard to do.
My advice would be to keep the article consistent, and not go overboard with unnecessary detail.
I wish you luck on writing the article and Happy Writing!
