About the Terraporters

The terraporters would be useless if it were not for the discovery of the crystaline terramite found throughout the Drowned Caverns.

The terramite crystals are largely inert and harmless, but once imbued with a still living soul they begin to radiate an intense energy.

The acquisition of a "volunteer" from Splitpaw is time consuming, and the imbuing process takes many hours of intense concentration by our shamans.

It is in our best interest to protect the terraporters and previously imbued crystals at all times.
