From Software will release a deluxe “Trilogy Box” set featuring the first three Dark Souls games and a host of extras, including a pair of bookends, six soundtrack CDs and a trio of books. The box set won’t come cheap; it’s listed at ¥49,800 (about $450).

The Dark Souls Trilogy Box will include a copy of Dark Souls: Remastered, Dark Souls 2: Scholar of the First Sin and Dark Souls 3: The Fire Fades Edition (the Japanese release that includes Dark Souls 3 and its downloadable content). Soundtrack CDs for each of those games are included, as is an item encyclopedia for each game. The box set also includes 10 art sheets and a special frame. One of the included bookends is sculpted to look like a Dark Souls bonfire, and the other a knight.
