Lost Ones

These were Wizards that were true to T'Let - thus O'Rahn - and decide to work for the greater good of Na'Syl'Nar and help the people creating a place to live. Once the world was progressing they dispersed to all areas of the continent and passed on their secrets to their families' or chosen ones' the Tairorca. These are like the holy monks of the land who have kept records of things since the time of O'Rahn.
They do know that magic exists and have some knowledge of it.
