Background
According to records kept by the Birthheart temple in Vasselheim, the Spire of Conflux born when the Melora breathed on a young beech tree during the Calamity. It was passed down from generation to generation of Ashari leaders.

The spire was lost approximately before 411 PD or prior to 536 PD, when Joran the Sea-Speaker, a respected leader of the Water Ashari, was devoured by a goristro named Yenk from the Abyss.

Scanlan used a Gate spell scroll to pull Yenk from the Abyss, using him as bait for Vorugal in the hopes that one of them would kill the other. The two giant creatures managed to do significant damage to each other. Vox Machina, with the aid of Lady Kima and Raishan, managed to finish them off. Once the battle ended, the Spire of Conflux was retrieved from Yenk's eviscerated belly and given to Keyleth.

When Keyleth jammed the Spire into a wound on Raishan's dead body, the black disease in Raishan's body suddenly accelerated, turned the entire body black, and withered the corpse to a husk.

Keyleth promised to return the Spire of Conflux to the followers of Melora in at the The Abundant Terrace when she finds its power is no longer necessary.

Post-campaign
Keyleth, still possessing the Spire of Conflux, takes her place as Headmaster of the Air Ashari in Zephrah. In 836 PD, rumors swirled that she was seeking another hero to wield it, one who can travel the land and do good in small ways as she once did.

Behind the scenes
If Vox Machina had not summoned Goristro to their plane, they would have had to go to the Endless Maze in the Abyss to retrieve the Spire. They would have needed to either to either find arcane means of tracking it, or make allies in the maze that could point them in the right direction (which often does not turn out well with demons).
