maybe I am being unlucky. I donated to the Priestess more than once, yet the hunts consist of glades, a mysterious cave, a path between the rocks, some ruins, helping Jaina and Rose, etc etc, but never the suppossed labyrinth cave I should find.
Got tired of hunting every day, so I saved the game where Eric is, ready to hunt, and I have all kinds of dungeons from the hunt but not that one.
Tea and Milk is completed, and talking to Fina looks like the usual talk. Maybe I am missing something. But I have all the initial quests completes, no Active quests at all. This is what the walkthrough says.
The case of the Order
The quest can be obtained while helping Fina with her mail after completing the "Tea and Milk"
quest and if Eric received an improved sword from the mysterious Priestess during your day hunt.
