Sentinel Prime

Introduction
The Sentinel Prime is the highest-ranking member of the Sentinels, the magical law enforcement of Atlantis.

Pre-ASFS
At some point between the establishment of Atlantis and its monarchy in 1709 and the present day, the Sentinels were created to enforce the law on both Atlantis and, when necessary, the world above the ocean. The Sentinel Prime position was made to manage Sentinel operations both in and out of Atlantis.

ASFS
Following the rescue of Mary Cassel, Joshua Hamilton promised Ash that he would 'put in a good word' with the Sentinel Prime to help him pursue his career as a Sentinel. This was either a bluff or overlooked by the Prime as it is not mentioned again.

Soon after the incident with Callum and the other Lycan, Sentinels Welsh and Marsh were dispatched by the Prime to retrieve them and bring them to Atlantis for questioning. This never occurred, however, as the group soon decided to head to Salem.
