The in-character rank of guild veterans. Members who have been with the guild for 4 years, or who have served as Primarch, Exarch or Archon.

Long term members of the guild are promoted to Pentrarchs. These individuals are usually well known by most members and are expected to hold strong to the guild ideals. All Praetors are monitored to an eventual promotion to Pentrarchs, if the Exarch Council deems them worthy of the honor. It is the highest rank given to members of Immortalis as they are granted extra privileges and greater trust is placed upon them to be an example to others.
