Prime Naaru are naaru found on Argus replacing Spirit Healers. Xe'ra was referred to by Turalyon as "the prime naaru", by Prophet Velen as "the naaru prime", and as "the naaru prime" again in Chronicle Volume 3. Xe'ra herself says she was "one of the first naaru to be forged during the great ordering of the cosmos."
- Khadgar believes that "the prime naaru" may have been forged by Elune; whether this referred to Xe'ra in particular or the prime naaru as a whole is ambiguous, though the former is likely since Khadgar was theorizing about using the Tears of Elune to unlock information stored within Xe'ra's core.
- All instances of "the prime naaru" or "the naaru prime" seem to be in singular and referring to Xe'ra. The presence of more Prime Naaru on Argus that are only visible when dead are the only exception.
- Patch 7.3.0 (2017-08-29): Added.
