Getting around Azeroth on a cool mount is half the fun in World of Warcraft, and the Stormcrow, Thrayir, Eyes of the Siren, is one of the coolest. This isn't the first raven mount, but Thrayir's unique, named after the Siren's Isle zone in the Warlords of Draenor expansion. Acquiring it involves navigating the island during a specific weather event, the Storm, which has multiple phases. You'll need to collect five Runekeys scattered across Siren's Isle while the Storm rages. Here's how to claim this awesome flying mount:
How to Obtain Thrayir, Eyes of the Siren in World of Warcraft

The Whirling Runekey: This key drops from Ksvir the Forgotten, a rare spawn found in the southernmost room of the Forgotten Vault during a Storm.
The Torrential Runekey: Collect seven Torrential Fragments from any enemy on Siren's Isle during a Storm phase.
The Thunderous Runekey: Gather five Thunderous Fragments from any chest on Siren's Isle—the chest's location doesn't need to be in a Storm area.
The Cyclonic Runekey: Fish anywhere on Siren's Isle during a Storm, or it might drop from Zek’ul the Shipbreaker in the Deadfin Mire.
The Turbulent Runekey: Find three Turbulent Fragments in these specific locations near Kul Tiran ghosts:
- Behind the abandoned inn, dig in the garden.
- Inside a cave in the Rotting Hole zone (the ghost is cowering inside).
- Inside the Spirit-Scarred Cave (the ghost offers the fragment).

Once you've gathered all five Runekeys, head back to the Forgotten Vault on Siren's Isle, but only during the Seafury Tempest phase of the Storm. Entering during any other phase won't trigger the ritual. Inside the Vault, go to the eastern room.
Thrayir's body will be on a platform surrounded by five runestones. Place each Runekey into its corresponding slot. This will initiate the quest, "Thrayir, Eyes of the Siren." Complete the quest, and the mount is yours!
