Shadow and Claw
“To the east of Dragonhead, near the southern cliffs of the Sea of Clouds, a significant rift in the aether has been detected. Through this rift, a massive horned demon and a small army of its invincible minions have appeared, posing a threat to the Ishgardian knights stationed at the outposts nearby. For the time being, the creatures appear content with remaining on their rocky outcropping, but for how long they will remain is uncertain. Engage the voidsent, ignoring the incessant hounding of the minions, and focusing your efforts on their leader.
