Post-Palace Questions (SPOILERS)

[Nalien]

Generally speaking, there is patch chronology... Something added in 2.3 happened after 2.2 and before 2.4... Tam-Tara (Hard) is in 2.3, Palace of the Dead is in 3.35, the fact that you can enter Palace of the Dead so early is a gameplay thing, rather than a lore one, it's there to let new players aren't left out of new content, and to give people the freedom to try out new Jobs with it. That you can enter without doing the dungeon doesn't really mean anything, the Estinien example has already been mentioned, but there's also the Culinarian quests; In both examples you have characters who shouldn't be there, depending on where you are in the MSQ, but both are 2.0 quests, they happen in 2.0, not 2.1 or 2.55 or 3.0... Thus, events beyond 2.0 do not impact them... They've already happened, regardless of whether you've done them yet... I see no reason why Tam-Tara (Hard) and Palace of the Dead would be any different, doesn't Edda (in Palace of the Dead) even directly reference her little tumble at the end of Tam-Tara (Hard)?
