Primordus was the first of the Elder Dragons to awaken in Tyria. Primordus' original resting place was in a cavern deep underground, where it was assumed by the asura to simply be a statue emitting a high amount of magical energy. For this reason, they built the Central Transfer Chamber near the dragon. Primordus was initially supposed to awaken in 1078 AE, but upon the defeat of its most powerful general, the Great Destroyer, its awakening was delayed by two generations, until 1120 AE. After its rise, the other Elder Dragons began to stir, one by one.
After its awakening, its minions, the destroyers, flooded the Depths of Tyria, crushing any hopes the asura had of returning to their natural home. Many of the remaining dwarves, now creatures of stone, stand watch at entrances to the Depths, ensuring that Primordus' minions never reach the surface. Others traveled into the caverns to do battle directly with Primordus and its servants.
Primordus has remained underneath the surface since its awakening, clearing huge tracts of the underground regions, which forced more races, such as the skritt, to flee from the Depths. As a result of its activities, the minions of Primordus can be found almost anywhere on the surface.
It is claimed in the book named The Elder Dragons that Primordus' previous awakening is the only one still known to history. Dwarven legends tell of Great Destroyers which are today believed to reference to Primordus and his armies.
- Primordus comes from the Latin root primordium, literally meaning the "first to rise."
