How to open the Rookery Cache in WoW Midnight

World of Warcraft Midnight has added a handful of different treasures for you to collect, tying into the Treasures of the Eversong Woods achievement, such as the Triple-Locked Safebox. While the others are located in the woods itself, the Rookery Cache is hiding away in Silvermoon City.

More specifically, it's atop a floating tower called the Sunwing Rookery in the Falconwing Square, located in the west of the city at the map coordinates 24, 69. You'll need to fly up here using your mount.
