How do you feel about Highborne RPers, since lore states that using arcane magic causes nelves to become highborne over the course of a week and nelf mages are now canon?
Well, technically the term “highborne” means “those of noble birth”. It’s a term used for the upper class of kaldorei that were born in that certain caste. A Highborne did not necessarily mean they are a mage or use arcane magics, but arcane magic is closely associated with the kaldorei Highborne because they coveted and monopolized the secrets of the teachings to themselves.
I don’t think, or perhaps simply don’t remember, that there is anything in lore that states those kaldorei that use arcane magic become Highborne, merely that they become kaldorei mages. However, the mage trainers in Darnassus (and some in Stormwind I think) are Highborne mages because they are Shen’dralar, a group of Highborne that have lived/survived/hidden in Eldre’Thalas (what we know as Dire Maul), lead by Mordent Evenshade. Most modern kaldorei mages are merely lowborn night elves that have learned arcane magic under the tutelage of the Highborne, but that does not necessarily mean they belong to the Highborne caste because they have to be born in that caste.
Some RPers have used the option of the night elf mage to play a Highborne returning to Kaldorei society, others that they are a night elf learning the arcane arts.
So, technically, Beurghes is and never will be a Highborne because he wasn’t born one. But he believes that since he masters nature magics that he is just as good as the Highborne and their arcane, and demands equal recognition and status.
