Game developer Atlus opened two teaser sites related to its Etrian Odyssey role-playing games. The first site shows a picture of a tree with a floating letter "D." The site's title is "Nobody knows the 'D'" in English.

The second site is the same but with a floating "IX" (Roman numeral for 9) and the title "Nobody knows the 'X'." The site originally had a floating "X" (10).

If the 'D' is also read as a Roman numeral, it is equivalent to "500."

Atlus will release Shin Sekai-ju no Meikyū 2: Fafnir no Kishi (Etrian Odyssey Untold II: The Knight of Fafnir) 3D dungeon RPG in Japan on November 27. Atlus USA released both Etrian Odyssey Untold: The Millennium Girl and Etrian Odyssey IV: Legends of the Titan last year.
