Culling the Swarm

This is an Act 3 main quest, offered by Douglass after completing Infested Fields.

Background
Douglass explains that the Dermapteran hives are cyclical in nature, and every seven years they birth a new queen who quickly proliferates their numbers. Prior to the Grim Dawn the farmers of Homestead would band together to destroy the Dermapteran queen to stop the reproductive cycle, but of late they have been allowed to thrive.

The Queen must be destroyed or the insects will soon run out of food and attack Homestead.

Objectives

 * Collect a Pheromone Gland from Grand Vizier Lozakal
 * Collect a Pheromone Gland from Grand Vizier Inixil
 * Access the Queen's Lair
 * Slay Swarm Queen Ravna
 * Return to Douglass in Homestead

Guide
Locate and enter the Royal Hive; the Cave Entrance spawns randomly in the upper northern part of the Rotting Croplands and you may need to explore several fields.

You will then need to kill two Boss creatures, Grand Vizier Lozakal and Grand Vizier Inixil, both located randomly within the Royal Hive, and collect their pheromone glands. These two quest items are required to unseal the Entrance to the Hive Queen's Lair. Once inside the lair it is best to skirt the left and right sides to clear out the Dermapteran packs before taking on Swarm Queen Ravna. After killing her report back to Douglass.
