Update on this: still haven't had time to put these into feature requests but it turns out the wiki does have the API installed which would allow the game to directly edit pages on the wiki.
And there's also an extension available which, if installed, could pull a page from the wiki as HTML to allow it to be viewed in game.
So perhaps this would be a solution to the database storage issue if more descriptions and fluff end up being added to the game. The description storage could be handled in the wiki but it could be created, edited and viewed in game via the API.
