Spiderweb Software announces Avadon 2: The Corruption, will be released on Oct 30th for Windows and OS X, with an iOS edition of their epic-length RPG sequel expected early next year, saying it "will be available on Steam as well as other sources and directly from the Spiderweb Software website." This trailer from a couple of months ago shows off the game, and here's a bit on what to expect:

As a Hand of Avadon, the Black Fortress, you once held unlimited power. Your word was law. Your homeland was united and prospered under the protection of the Black Fortress. Now that fragile alliance has collapsed. Rebellion rages, outside enemies gather, and Avadon lies in ruins. Will you fight to restore your power and bring peace to your realm, or will you join the rebels and forge a new nation? The decision will be yours in Avadon 2: The Corruption.

Avadon 2: The Corruption is an epic fantasy role-playing adventure in an enormous world. Choose from five different types of characters, including the new Tinkermage class, each with dozens of unique spells or skills. Explore a gigantic world filled with secrets, artifacts, and a rich story. Experience multiple different endings and ultimately choose between saving your homeland or allowing it to fall and make way for something greater.
