The Crown of Heaven

The Crown of Heaven is offered by Wrathion part way through the Patch 5.2 portion of his legendary quest. To get to this point, champions must have completed the Patch 5.0 and Patch 5.1 portions of Wrathion's quest, Breath of the Black Prince (quest) and Call of the Packmaster / The Soul of the Horde respectively, acquired twenty Secrets of the Empire from raid bosses in the Throne of Thunder (alongside 40 Trillium Bars), reached standing with him by killing mogu, saurok, Zandalari troll, and opposing faction players on the Isle of Thunder, unlocked the Thunder Forge, and killed the world boss Nalak.

Once all of those trials have been accomplished, Wrathion will award a selection of legendary meta gems. His quest is not complete, though, as he will immediately turn around and ask for twelve Titan Runestones from the last six bosses in the Throne of Thunder for future purposes.
