If you travel to obsdian.net right now you will be greeted with a mysterious countdown accompanied by a few ominous words.
The exact words are as such:
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.
Now what does this mean? Most probably it is a countdown to an unveiling of a new Obsidian game, Project X. If more evidence was required, then you only have to click on the logo in the center of the page which will take you to a speculation forum for the so-called Project X.
We will have more details as they come forth.
