1) The general backstory behind Trove. That would be the nature of the Moon Goddess's "betrayal", how she stumbled upon the Shadows, Q'bthulhu's attack, and the Sundering, leading up to the current state of the world. Essentially, everything covered by Qubesly's retelling pinned in the Discord server. People very commonly think that the Moon Goddess is outright evil and/or that the Moon Goddess and Daughter of the Moon are the same being; having the correct story being more public would be nice.

2) The story of the Desert Frontier/Steambots > Neon City > Amperium/Luminopolis/Resistors is often asked about, and is also one of the topics that we have the most lore about, so it would be a good topic to gather information on.

3) Geode is also one of the topics with more lore than usual, and its story is fairly interesting as well. I'd like to see what we have on that compiled too.

As for presentation, just a simple text story should do. I see a few other comments suggesting cutscenes/video presentations, but those would probably be a pain to make and even moreso to update as new lore is added, so it really probably isn't worth the effort. Adding relevant images might work, though. I'd recommend listing every source of information used somewhere, from item descriptions to quotes from Atronos.

I'd put a place somewhere on the site for user-submitted fan theories, maybe with sorting/rating/commenting systems, but not officially list anything that isn't explicitly spelled out by an official source. For instance, I've often mentioned on the Discord that the Daughter of the Moon is a creation of Q'bthulhu using the Moon Goddess's stolen power, but it isn't directly stated, only implied, so it still wouldn't be mentioned anywhere.

Somehow the "Ol' Gold-on-Green" highlands decoration got into the Sails list labeled "Basic Sail".

You should fix that, and check if there are any other "leaked" nonexistant items like that.
