Background
The staff was born from Melora's breath during the Calamity. It was lost approximately before 436 PD or 536 PD when Joran the Sea-Speaker, a respected leader of the Water Ashari, was devoured by a goristro named Yenk of 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 at the The Abundant Terrace when she finds its power is no longer necessary.

Keyleth, still possessing the Spire of Conflux, takes her place as Headmaster of the Air Ashari in Zephrah.
