Secundus

Secundi were the most powerful of hierarch modrons. They were second in power only to Primus itself.

Description
Secundi appeared like very thin and tall humanoids, with long faces and deep-set eyes.

Society
There were only 4 secundi in modron society. They could communicate with other secundi and relayed their orders to tertians under their command, but reported directly to Primus itself. Each secundus was a viceroy in charge of one of the four quarters of their realm in Mechanus. They could communicate telepathically with anyone in a 420-mile (676 km) radius.

Secundi were always created as the result of a tertian being promoted to take the place of a killed or further promoted secundus. If Primus died, one of the secundi was promoted and took its place as the new Primus.

History
Around -346 DR, Netherese archmage and explorer Lady Polaris came upon Mechanus and the modrons. She summoned several decatons to her home to guard her treasures, but was stymied as they kept disappearing after several days. She suspected that a secundus was behind the disappearances as a form of extraction, and later had more sucess with the pentadrones she focused on next.
