Myrmidex Threat

A folio of the realm

Myrmidex Threat

The Myrmidex Threat is the Eodon -arc faction conflict that pits the Eodon tribes and Britannians against the Barrab tribe and the insectoid Myrmidex. The Valley of Eodon has been besieged by a Myrmidex invasion and players choose a side by visiting one of two allegiance idols in the Valley. Allegiance can be switched, but only once every two hours, and the choice gates which of two parallel quest chains the player can undertake.

Both alliances are entered through the Myrmidex Pits, a battle-instance underground arena where the player and their faction's NPC line push the opposing front line back. Only after winning a pit battle does the post-victory quest chain unlock for that alliance.

The Two Alliances

Eodonian Alliance

Side with the Britannian-Eodonian coalition by double-clicking the Alliance idol banner, then enter the pits via the excavation site west of Sir Geoffrey's camp. Sir Geoffrey's camp sits northwest of the Kurak Village and east of the desert surrounding the Barrab plateau.

Inside the pits, the player's targets are:

  • Barrab warriors and mages
  • Myrmidex drones
  • Myrmidex warriors

Britannians and all other Eodon tribesmen fight alongside you — don't kill them. Push the opposing front line back to win the battle. Victory unlocks the post-pit quest chain Exterminating the Infestation.

Myrmidex Alliance

Side with the Barrab-Myrmidex coalition by double-clicking the Myrmidex idol, then enter the pits via the lift platform in the southern portion of the Barrab Village.

Inside the pits, the player's targets are:

  • Britannians
  • Members of the other Eodon tribes (Kurak, Urali, Sakkhra, etc.)

Myrmidex and Barrab tribespeople fight alongside you — don't kill them. Push the opposing front line back to win the battle. Victory unlocks the post-pit quest chain The Zealotry of Zipactriotl.

Switching Sides

Allegiance can be switched by visiting the opposing idol — there is no penalty beyond the two-hour cooldown between switches. Players who want both quest chains can rotate alliance after each pit-victory cycle.
