Obsidian Entertainment has announced Pillars of Eternity expansion The White March - Part 1, which is "coming soon" for PC (Windows, Linux) and Mac.
Obsidian CEO Feargus Urquhart said it's the first part of the expansion they're doing for the game - a comment that will need more explanation - as will him claiming Obsidian did more writing for it than for the main Pillars of Eternity game.
The White March - Part 1 will raise the game's level cap, add new multi-class abilities, new companions (including rogue and monk), a new party-based AI system and more.
The story of The White March - Part 1, as gleaned from a short trailer, involves you breaching an old fortress and finding a white forge within. Presumably riches await.
