Cannot take part in Fyrakk Assaults

Fyrakk Assaults won't begin until the next part of the campaign quests are available during the week of the 8th of May after weekly resets, as the forces of Fyrakk are still mustering.

Once the story arc The Ancient Bargain has been completed, the Mirror Image of Kalecgos in Loamm should offer you the quest Fyrakk's Forces, which introduces Fyrakk Assaults and allows you to join the fight against them for great rewards!
