Troll Hives

Troll hives are filled with green jelly that has tiny bubbles with a soft white glow. This solution is kept at 150 degrees. They are used in Flashback to save Luna and Wynn's lives.

History
Several thousand years before the books take place, the troll hives were raided by ogres. The trolls managed to fight them off and mantain control of their lands, but they lost the entire generation in the process. To prevent this tragedy from repeating itself, Luzia Vacker helped them to hide their hives with illusions at Everglen near the lake. When more space was needed, they moved the hives to Dawnheath. A troll hive was discovered in Flashback to still be on the property of Everglen, covered by Luzia's illusions. The trolls from the hive destroyed much of the property. Later in Flashback, it's revealed that Luzia had another hive hidden near the overdrive where Luzia and Empress Pernille were secretly trying to design trolls that were both smart and strong when they were newborns.
