There are several hidden locations that can be discovered throughout the game:
To make them visible:
- An NPC traveler in the tavern will offer you an 'opportunity' for 200 denars. Usually this will net you some troops or a map to a chest. However, in one instance you may obtain a map to the Red Brotherhood Hideout, the location will then disappear.
- You must gain favorable relations with the Noldor (15 relation) at which point Quigfen will give you a quest to defeat a marauding Jatu army. If you succeed, the location will be revealed to you.
- Brother Randalf in the tavern will offer you the location in return for a Qualis Gem. The location can be one of two general areas: deep in the D'Shar desert beyond Torbah, or at the far corner of the Jatu foothills between Laria and Poinsbruk and more rarely above Cez.
- The Snake Cult Stronghold can only be found following the Order Grandmaster Quest of a Knighthood order. Its initial garrison is 1000 troops strong, after each failed attempt to storm it the snake cult increases its defenses so make sure to field a large number of elite troops.
