Lost Legion Infernals
While in outdoor zones in Remix, you'll sometimes see the message Lost Legion Infernal begins phasing into this timeline.... This message indicates a Lost Legion Infernal is spawning in your zone. You can see its location on the minimap.
As the vignette suggested, Lost Legion Infernals have health pools similar to World Bosses and scale with the number of players in combat with them. They have different affixes every time they spawn, similar to Obelisk Doomguards. Unlike world bosses or rares, however, you receive loot from Lost Legion Infernals every time you defeat them. Their loot is as follows:
20x Fragmented Memento of Epoch Challenges
4x Flawless Thread of Time
Stamina Mementos for your Artifact
1250x Bronze
1100 to 1200 Infinite Power
Their spawn rate seems to be tied to the amount of activity in the zone. This means realms with a lot of players will see Infernals spawning back to back, while smaller realms might have breaks between spawns. Overall, they are up very often.
Weekly Quest
Before going on an Infernal spree, head to the Infinite Bazaar, where Moratari has a new quest for you: Out of Time. This is a new weekly quest that asks you to slay a Lost Legion Infernal.
Defeating the Lost Legion Infernal will complete that step and drop a Blank Doomsayer's Pamphlet, which you can bring back to Moratari. By doing so, she will have a couple of dialogue options explaining what the pamphlet is.
Picking any options unlocks the next step to burn the pamphlet at the bonfire in the middle of the Bazaar. When doing so, you'll be prompted to put a message in the pamphlet before burning it. Depending on what option you pick, a different message will be broadcast to everyone in the Infinite Bazaar. These range from showing off your stats in Legion Remix, to silly ones.
Dialogue implies that this is a weekly quest, so you will have the opportunity to send at least a couple more of these messages to your realm before the end of Legion Remix. What message are you sending to your realm?
