Patch 10.2.7 introduces World of Warcraft Remix, an event where we'll revisit Mists of Pandaria. Unlike Plunderstorm, Pandamonium has some lore behind it, explaining why we're investigating the past.
The main character behind Pandamonium is Eternus — an Infinite Dragon who the Bronze dragon Chromie recently befriended. Up until recently, all members of the Infinite Dragonflight have been the Bronze flight's deadly enemies — seeking to destroy the timeline the Bronze are tasked with preserving.
Chromie met Eternus during the Thaldraszus Big Time Adventure questline. The two became trapped in a time anomaly during an Infinite attack on the Bronze — sending them through various timeways together while we tried to save them. Due to having to rely on each other — at least for as long as it took to rescue them — Eternus and Chromie formed an obvious bond.
Through this friendship, Chromie came to understand Eternus, and advocated for Nozdormu to spend some time with her and hear her point of view. Nozdormu agreed, and even revisited the past with Eternus to examine the incident that caused her to deflect to the Infinite in the first place. Like all Infinite, Eternus was a member of the Bronze flight once — along with her sister, Moraidormi. But when Moraidormi was killed by the Black Dragonflight, the Bronze refused to allow Eternus to change time to save her — even though they have the power to do so. Eternus could never understand why it was so important her sister die, and so never forgave the Bronze's rigid views on the timeline.
By revisiting the incident, Nozdormu helped Eternus learn something she didn't know before — that Moraidormi had sacrificed herself willingly to save a Bronze whelpling. Eternus realized that she had to accept her sister's choice, and this finally helped her make peace with the timeline. At the same time, Nozdormu realized that the Bronze have been too rigid. Oddly, Nozdormu came away from the exchange
