Before the Clans retreated to the Training Camps, they were found above ground. Following is information on the early locations of the 6 Clans, provided for historical reference.

Each of the 6 Tumerok Clans can be found in different geographic locations throughout Dereth. Each Clan will have Standard Bearers, Majors, Lieutenants, Commanders and Controllers. The Tumeroks in the lesser Clans are of lower levels than the Tumeroks of the more dangerous clans, even if they are called by the same name: you'll find Tumerok Standard Bearers of Level 15 (for Falcon & Serpent), Level 35 (for Shreth & Reedshark Clans) and Level 45 (for Gromnie & Mask Clan). 

Each Tumerok will be grouped with its level counterpart (i.e. Level 15 Standard Bearers will be grouped with a pair of Level 15 Tumerok Workers). The highest level Tumeroks are extremely dangerous. They carry Quiddity Weapons and are strong enough to activate the spells!

Tumerok Tribe Locations:
