While Black Temple Timewalking can award 493+ item level gear this week, we've also confirmed that the Cache of Timewarped Treasures quest reward can also drop the elusive Ashes of Al'ar!
Courtesy of and congratulations to Skiko!
In over a decade since the Burning Crusade, the Ashes of Al'ar are not particularly difficult to obtain at this point, as virtually any one at or near max level can quite easily solo Tempest Keep and defeat Kael'thas Sunstrider within, it remains a rare and highly coveted mount. Although a common misconception, it does not drop from Al'ar itself.
Despite popular misconception, the Ashes drop from Kael'thas rather than Alar.
Whether or not you are particularly interested in this mount, it's a good idea to head over to Shattrath and pick up Disturbance Detected: Black Temple anyway.
