A master has to sponsor you to Re’lar. So you should pick one and stick to him like shit on his shoe.
To become a Re’lar, you must be sponsored by a Master of the University. The word Re’lar translates as “speaker,” its etymology lies in the title originally being granted to those who knew at least one Name. As Naming is far less common in modern times, it is no longer necessary to know a name to be promoted.
It has been suggested that a span of six terms as an E’lir is normal before advancement, though the length of time could vary considerably, depending on both the student and the master.
