Deep in the Amazon rainforest, ancient tribes spoke of a massive guardian creature that protected the forest's secrets. The Wildwood Guardians discovered that this Mapinguari shared a spiritual connection with Sasquatch, leading to the establishment of a cross-continental alliance of cryptid protectors. This alliance became formalized through the position of the Mapinguari Sentinel.

The Mapinguari Sentinel possesses the ability to communicate with both Sasquatch and their South American counterpart, serving as a bridge between two ancient traditions of forest protection. They carry sacred totems from both cultures and can navigate the spiritual pathways that connect the world's ancient forests. Their presence is marked by a distinctive scent of ancient growth and mystical energy that other guardians can sense.

The Mapinguari Sentinel serves as a diplomatic link between North and South American cryptid protectors, sharing ancient knowledge and coordinating joint preservation efforts. They maintain the delicate balance between revealing enough to protect these creatures while keeping their deepest secrets hidden from those who would exploit them.
