In the world of Tamriel, magic is a very common thing and it wouldn't be surprising to see marketplaces dedicated to the mystic arts. One Elder Scrolls Online player has created Diagon Alley, the famous magical marketplace from Harry Potter, in the game.
The Elder Scrolls Online features plenty of activities for players to do, one of which is homeownership. Known as the Homestead system, this system lets players buy and decorate homes ranging from rooms at an inn all the way up to manors. However, players don't necessarily have to make their home a house. A Reddit user named Hachiko_Chan has managed to bring Diagon Alley into the world of The Elder Scrolls Online. Hachiko's work was done entirely with furnishings and armor players can get in-game, along with the normal housing editor tool. This project, which was posted a few days ago, has been 98% upvoted by members of the Elder Scrolls Online Reddit community.
Hachiko mentions in the comments to their work that they're planning on doing a sequel piece to Diagon Alley. Harry Potter has plenty of iconic locations that are all worthy of being recreated in any game that lets players build their own housing. Quite a few folks in the comments suggested that Hachiko next builds Knockturn Alley, the seedier side of Diagon Alley frequented by morally questionable magic users. In the world of Elder Scrolls Online, it would most likely be where all the necromancers hang out. Hachiko mentions that the plan was to originally make Knockturn Alley and include a passage to Diagon Alley, but could only choose one of them because of the slots limit and their "madness for the details." However, the idea to make Knockturn Alley is still there, and they might make it next year as a Halloween project.
