EQ4

From Wikipedia of the Dark Brotherhood, an online Star Wars Club

Sith Warlord, Obelisk Primarch, or Krath Pontifex (commonly known as Equite 4 or EQ4) is the twelfth rank in the Dark Brotherhood. It is the highest rank of the Equite class.

All of these ranks are equal.

At this rank members may request custom Dual Lightsabers.

It follows Equite 3: Sith Battlelord, Obelisk Exarch, and Krath Epis.

It is followed by Dark Side Adept.

For a while between 2003 and 2005, this rank was instead at Equite 3.
