Simply known as the Master, he is a well established leader of the The Watchers of the Midnight Eye and the guardian of the masks. Training those of divine blood and those chosen by the gods to wear the divine masks, he observes and maintains neutrality.
When new chosen came before him, he challenged them to complete the trials. Not all of the adventures completed the trials but most humored him. However, the one who didn't compete in the trials managed to break into the secret vault. This infuriated the Master considering how they originally came to ask for his help. With the smooth words of Leviathan Jormun, he regained a small sense of trust within the group and assisted them on their journey.
The Master would later break his vow of neutrality and engage alongside his Watchers within the 2nd Demon war.
