Gabrinko, also known as the Hidden Sage, is a wood sprite who lives in a cave on the island of Omari, near the summit of Mount Dagaro. He resides on the top of a stalagmite, his brown, shriveled texture camouflaging him well. Standing up, he would be about the length of a pointer finger, looking almost made out of wood. His kind considers him an outcast.
Gabrinko helped Seth with his memories and provided him with the information that it was the demon Humbuggle that had previously put the curse on him and told him that the demon now resided at Titan Valley. He also informed Calvin that he sent Serena to the same dragon sanctuary.
