McQuaid describes the Pantheon: Rise of the Fallen as "challenging planar high fantasy", although it's hard to work out much more about the game's world from the limited scraps we've seen so far. Here's a man in a chair.
Pantheon: Rise of the Fallen. Ok, game twitter acct found early, lol. Looking forward to letting you guys know a lot more than just the name— Brad McQuaid (@Aradune) January 3, 2014
McQuaid also confirmed that the game is not owned by Sony Online Entertainment, who published Vanguard, and that there's a "minimum of 3 years to release", although a beta is incoming.
There's a Kickstarter campaign planned (of course), so we should find out more info in the coming months. In the meantime you can keep an eye on the, which should become active soon.
