It's not much to go on, but Obsidian Entertainment is teasing a new RPG on their company web site. Seen in the cryptic tease is the number 4 and some obscure text about the Dirge of Eir Glanfath. Seeing as Obsidian worked on Dungeon Siege 3 for Square Enix, it isn't much of a stretch that the 4 could mean the next installment to the fantasy RPG series.
The site offers the following: "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."
A quick glance at the source of the webpage offers this additional snippet: "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."
