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 its Siren Isle origins make it special. This mount is tied to a weather event called the Storm, occurring in phases within the Warlords of Draenor zone. You'll need to collect five Runekeys scattered across Siren Isle during these stormy periods. Here's how to snag this awesome flying mount:

1. 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.
2. The Torrential Runekey: Collect seven Torrential Fragments from any enemy on Siren Isle during a Storm phase.
3. The Thunderous Runekey: Gather five Thunderous Fragments from any chest on Siren Isle—the chest's location doesn't need to be within a Storm area.
4. The Cyclonic Runekey: Fish anywhere on Siren Isle during a Storm, or it might drop from Zek’ul the Shipbreaker in the Deadfin Mire.
5. The Turbulent Runekey: Find three Turbulent Fragments in these specific locations near Kul Tiran ghosts:

Once you've gathered all five Runekeys, head back to the Forgotten Vault on Siren Isle, but only during the Seafury Tempest phase. Entering during other phases won't trigger the ritual. Go to the eastern room of the vault.
You'll find Thrayir's body on a platform with five runestones. Insert the corresponding Runekeys into the slots to begin the "Thrayir, Eyes of the Siren" quest. Complete the quest, and your new mount will be added to your inventory!
