Why Tyria Has Not Been Desolated
The most important question if Primordus can wipe out all races in Tyria why has he not attempted to do already? The answer is simple the right circumstances have not occurred. We are able to infer based on current lore that the Elder Dragons themselves are probably as intelligent as an average human in Tyria which means they have the capacity to act intelligently but do not because they lack knowledge and to not pursue it. If Primordus can produce a lieutenant that can act tactically and systematically he would become the most dangerous Elder Dragon
The only instance found of Primordus obtaining a sapient minion is the Imbued Grawl Shaman in fractals and that is technically not canon in open world. According to Ree and Jeff Grub Primordus has the potential to obtain sapient minions like Jormag via similar slow corruption method.
Primordus in particular of all Elder Dragons employs the least intelligent minions because his personality is not conducive to generating and obtaining them unlike Zhaitan who corrupted Orrian royalty and some great military commanders.
Requirements for Doomsday Scenario and Tactical Victory
Primordus grawl fractal events happen and the newly imbued Grawl tribe sacrifice more intelligent races into corrupting lava pits producing a minion with enough scientific intelligence or military knowledge to lead the Destroyers on world extinction campaign.
Primordus Doomsday Scenario:
Provided the right circumstances and logistics, Primordus can use destroyers to agitate major volcanoes to cause mass extinction of all terrestrial races. The simultaneous eruption of many volcanoes would cause the world to be filled with ash wiping major parts of arable land in Tyria ensuring long term victory by making it impossible for advanced civilizations to thrive. Short term any volcanic activity near civilized nations would cause cataclysmic results crippling said nations. Therefore if the doomsday plan ever successfully starts Tyria is screwed.
Tactical Victory:
Under the guidance of an adept military commander Destroyers would be neigh undefinable in guerrilla warfare. Destroyers have shown that they currently dominate subterranean Tyria. with over a century to expand and takeover previous underground races’ tunnel networks and build their own they have the capacity to to strike anywhere in Tyria. Using these networks the newly recruited military leader would employee scorched earth campaign of resource denial with little fear of retaliation from the races’ Tyria.
Divinities reach may be heavily fortified but surgical strikes on its farmlands would cripple humanity due to food shortages. The Asura reside in Metrica which is dense in fauna systematically causing of forest fires could desolate their land making it difficult to obtain special resources crippling their economy and abilty to make deus ex machina solution. The Pale tree is a kitten plant kamikaze destroyer crabs into its roots until they are so degraded it dies without her the entire Sylvari race is destined to be extinct.
The Norn and charr are more difficult to lead a successful military campaign against. Norn individual strength enables them to more successfully deal with the Destroyer hit and run tactics. The Norn are not reliant on farming and live in a cold climate. The Charr have vast land holdings and better equipped to secure food than humans versus a Destroyer scorched earth guerrilla campaign. If campaign against the humans, Sylvari, and Asura is successful. The Charr war-machine should not be able to successfully mount any underground assaults and the Norn are not organized enough or suited for underground excavation and combat. bear in mind I assume that other dragons are still active and that Merdremoth has been dealt with. Thus Primordus would likely achieve a military victory over span of decade.
