As told by Daruus Tor-Rexas

The Twilight Circle is an organization created to study the magical arts. Founded in Durbin after the last changing of the age, they were responsible for the creation of the newest versions of Enchant and One-Year Extend rituals as well as Summon Fire Elemental. They have created others too numerous to tell. To this day, they remain dedicated to the study and creation of new spells, and the spread of this information. Many of its members travel the world seeking new members and artifacts to study. They often pay adventurers to seek these artifacts, preferring to face the dangers of magical experimentation rather then those of the outside world.
