The Obsidian front page has been replaced by a mysterious countdown site which has a dragon chewing its own tail with a number four also featured.
There are also mentions of Project X, which might mean that the company is working with publisher Square Enix on a new title.
The front page also reads: “What do the words mean? Nothing. The Dirge of Eír Glanfath is sound without form, a lone voice crying out in mourning because it must.”
The source page includes the following message: “To tenderness, fellowship. To fellowship, vigilance. So bring we all to the Night Market. I am the Spindle of Esenath. Know me by my light and stand with me in darkness.”
Previous speculation suggested that Obsidian might create a new Dungeon Siege game or a new Wheel of Time title.
The company is best known for working on games like Knights of the Old Republic II, Neverwinter Nights, Fallout: New Vegas and Alpha Protocol.
