Tears of laesa
Find the secret locations:
There are a few secret locations hidden on the continents. You may try wandering for one or, more reliably, try the randomly found maps. X marks the spot!
Explore the wilds:
Each of the secret locations contains a small area. At the end of each area, there is a Tear of Laesa, or a piece of fulgurite if you prefer the more mundane name.
To complete the quest, visit all the different kind of areas, and be victorious in reaching the treasure first, or at least be a member of the party doing so.
Don't despair! This quest will likely take for a while to complete. May the goddess Laesa smile... err.. weep upon you!
