Sept of the Hollow Heart
From Bluepelt Wiki
This Cearn is hidden deep in the Amazon rainforest, near Tefé (Brazil), and is build high up in the trees. They are a Cearn of cunning, where many tribes make their home. If they do not wish to be found, the chances of finding them are nigh to zero. It is said that this cearn has befriended many Fera in recent months, working together to defend both the Cearn and the ancient trees.
