Aveyond 3: Orbs of Magic
Mel has made a name for herself as a thief on the streets of Harburg. Hired to steal a family heirloom from a supposedly haunted keep, the job goes south when her client reveals himself to be a vampire determined to use Mel - and the dark prophecy entwined with her family lineage - to take over the world. Mel escapes, but is left with the job of preventing her family's curse from coming to fruition.
This game has four chapters: Lord of Twilight, Gates of Night, The Lost Orb, and The Darkthrop Prophecy. They're all reliant on each other and should be played in order, although the game will provide you with information to catch you up to speed if you start in the middle.
Game information and resources are divided by chapter.
