It's impossible to achieve 100% map or treasure completion on a first game, as numerous areas are sealed off with the "Rood Inverse." Given that you've finished the game, Ashley will be able to enter areas sealed with the Rood on subsequent playthroughs. This will eventually lead to the Gold, Platinum, and Steel Keys, as well as the Sigils needed for the time trials in the Keep.
Much of the undiscovered map is the result of areas sealed with the Rood Inverse, although a first playthrough can yield somewhere around 85%, if I recall correctly.Quote:
