Fourth Boundary announced on October 5 that it will run "Edda's Bag," a collaboration ARG with Square Enix's Final Fantasy XIV, as an advance implementation at Final Fantasy XIV Fan Festival 2026 in TOKYO. The event runs October 31 to November 1 at Makuhari Messe International Exhibition Halls 1-7. Participants receive a real "Edda's Bag" and walk the venue while accepting quests on their smartphones, an experience that carries FFXIV into the physical world. The work mixes elements of Fourth Boundary's Hito Series, such as Hito no Saifu, with tour-style content. Fourth Boundary warns that danger may befall players themselves and their characters, and that the piece contains horror elements on the level of the FFXIV dungeon The Tam-Tara Deepcroft (Hard) and related quests. To take part, attendees need a Fan Festival two-day pass plus a separately sold Edda's Bag experience ticket. Regular tickets cost 4,400 yen and PT tickets cost 11,000 yen, both tax included.
Two ticket types split the experience. A regular ticket covers one participant and one Edda's Bag, and attendees who want their own bag need one regular ticket each. The PT ticket is priced at 11,000 yen and lets up to four people take part, but the group receives a single bag. Advance reservations will open at a later date, and same-day tickets are planned for sale at the Fan Festival venue.
Fourth Boundary says the experience includes some puzzle-solving, with a hint function made extensive enough that people who are not good at puzzles can still take part. The announcement recommends playing The Tam-Tara Deepcroft (Hard) and its related quests first, since Edda's Bag contains expressions that touch on that content. An online version meant to be played from home is also in the works, with content and price planned to differ from the venue project. Tickets for the Fan Festival two-day pass have already sold out, and resale runs until around 23:59 on Sunday, October 18.
