The 5.2 dungeon looks like it'll be a lore bomb

I saw someone wondering if the Star in the patch title might actually be referring to the Shard that was destroyed in the previous Calamity, hence Dalamud being in the patch art.

Echoes of a Fallen Star could refer to any one of the Shards that's been rejoined, and Echoes can also have a literal (in the context of the WoL which the Devs have implied is so) as well as a more metaphysical meaning. Since the dungeon is Amaurotine, I'm inclined to hope it's referring to the original star, of which Zodiark is the Will of the Star made manifest, and so maybe we'll get more detail about the causes of the Terminus event. Any info on that would be grand. But everything is speculation.

Two side notes - Dalamud was never seen as a star, it was the lesser moon, so I'm doubtful about Dalamud being relevant. But yes, we are going to Bozja so they could be using falling heavenly bodies as a thematic device. Also our original Echo vision in 1.0 (possibly of the Terminus event? Possibly of the Battle of Silvertear?) also featured what are commonly called falling stars

That is a possibility, and would make a bit of sense with the possible image of Dalamund in the artwork.
