Runes of Camelot is a match 3 game that takes you on a journey through the Avalonian world. You can choose either Amelia (Merlin's magical apprentice) or King Arthur himself, to battle you way through the mystical, and magical, lands of Camelot, using the Magic Runes to defeat those who stand in your way.
This is the Isle of Avalon. It's the quest map of your chosen character.
