This is an optional side quest of the Olthoi Queen that gives items redeemable for one point in a particular skill (essentially being an experience reward equal to the cost of the next point in that skill). After the fifth and final bell has been handed, progressive olthoi spawns begin to appear across the entire Marae Lassel Plateau. There are five regions and each is independent of the other. These regions remain active until all stages have been advanced and the tesserae bearing Olthoi Brood Nobles killed or when the Queen is killed.
