Wiki-hosting service Wikia is launching a brand-new feature that lets users collaboratively annotate maps of just about anything — and that includes nerdy fictional locations like Game of Thrones' Westeros or even the inside of the Millennium Falcon. Though it only recently launched, the new section of the site already includes a number of user-created maps that give you a good idea of what's possible. A detailed cut-away image of the Millennium Falcon, for example, has such nitty gritty details that you can read about the ship's freight loading room or check where all of the exits are.
There are also numerous maps from the video game worlds of Dark Souls, Elder Scrolls, and Liberty City, and of course there are a few based on real-world locations as well. You can delve into a map of where every team in the 2014 World Cup is located, or check out where some of your favorite recipes come from, with helpful filters like wine or barbeque that let you narrow things down. The maps are also embeddable so that they can be shared relatively easily — after a recent open beta the feature is now live to everyone.
