Notes
Originally, the Matron Dungeons (see also Matron Hive West, Matron Hive East and Matron Hive North were located on Asheron's Island and had upper level restrictions. The dungeons only spawned the Matrons after one in the lower level dungeon was killed. Only after getting through the exit portal, you were flagged to enter Asheron's Castle. The Matron Hive South was located at 15.9S, 73.7E, restricted 20-50.
During the Into the Darkness event, the level requirement was updated from 20-40 to 20-50.
During the Visions in the Darkness event, the upper level requirement was removed (20+) and the portal moved to Nanto.
During the From Darkness, Light event, this dungeon's restriction increased from 20+ to 40+ and was repopulated with new creatures.
