With only three characters remaining, I decided to push them all through the Falling Star questline — get that mini-progression goal wrapped up — before having them continue on to level 102 and acquiring the rest of their Artifact weapons.
As I’ve taken more and more characters through the Battle of the Exodar, I’ve begun to imagine that what really happened was something like this:
When the Highlord recovered the Mysterious Lightbound Object and brought it to Khadgar, the two of them saw the vision of Turalyon together. Khadgar then summoned the other eleven Order Hall leaders and sent the twelve Order Hall leaders to the Exodar as a group. Upon arriving and discovering that the place was under Legion attack, they organized themselves into a Flex raid.
The Highlord and the Grandmaster were the tanks. The Farseer and the High Priest were the dedicated healers, with the Archdruid as the swing healer. The Battlelord, the Deathlord, the Slayer, the Shadowblade, and the Huntmaster were melee DPS. The Archmage, the Archdruid, and the Netherlord were ranged DPS.
The Archmage, who had been to the Exodar before (in disguise) and was anxious to find her Draenei Mage friend, helped the group navigate the unfamiliar halls.
When the Order Hall Champions arrived just in time for the final confrontation with Rakeesh, the group expanded to a forty-person raid, with each Champion taking a role appropriate to their specialization.
It was a somber group that returned to Khadgar in Dalaran, bearing the news of Velen’s grief. When Khadgar recommended that Light’s Heart be kept at one of the Order Halls, the immediate suggestions from most of the group were that it be kept at Netherlight Temple or the Sanctum of Light. The High Priest declined, saying that Velen was a frequent visitor at Netherlight Temple and she wished to spare him the renewed sorrow of seeing Light’s Heart again. They decided that the Order of the Silver Hand should keep the object.
This turned out to be a wise decision. After the Highlord placed Light’s Heart in the Sanctum of the Light, when Arator the Redeemer approached it, another message appeared… a message specifically for the young man, from his long-lost father.
It was only much later, when Khadgar suggested that the Tear of Elune be used to attempt to activate Light’s Heart, and Xe’ra revealed herself and her motives, that the Slayer claimed the right of keeping Light’s Heart… because, after all, the whereabouts of Illidan Stormrage was her Order’s special concern.
