The mount is attached to a letter from the renowned dwarf explorer Brann Bronzebeard, and reads as follows:
Glory of the Ulduar Raider (25 player)
I hope ye're doing well and that ye've had time to recover from our shennanigans in Ulduar.
Me lads from the prospecting team happened upon this poor 'alf dead riding-drake hatchling. Must've been an Iron Dwarf experiment of some sort.
We've patched him back to health and you'll find he's not so wee anymore! None of us knows much about riding anything but rams and pack mules and since we owed ye one for what ye did back there... we thought perhaps you'd accept him as a gift.
Blizzard officials have announced they do not have any current plans to remove the proto-drake reward.
Glory of the Ulduar Raider Reward Update | 2009-07-22 17:04 |Eyonix
After further discussion, we decided not to remove the rusted and [ironbound proto-drake] rewards for the normal and heroic Glory of the Ulduar Raider meta achievements when patch 3.2, Call of the Crusade, launches, and currently have no plans to remove them in the foreseeable future. However, we will continue to evaluate the situation and if a decision is made to remove these rewards at any point in the future, we'll provide a one month warning so players will have time to make some final attempts.
