... but right-clicking the Map allows access without doing anything about the quests.
This made me think about how the game's quests and epic quest lines have ended up a mess ...
There's actually an epic quest line to this story before reaching Shaarledah. A player finds that's there's three naga brothers and the BIG brother is Shaarledah. (No more spoilers .... )
So, anyway ... I believe the importance of questing and following quest lines is undermined by the player's thrill to get into instances that they know nothing about just to get good gear and mems. Unfortunately, players get comfuzzed about what to do in the game because higher level players try to rush them through attunements.
Could this be a result? Probably.
I do not know the original OP or their methods of questing and playing the game, but I do believe the percentage of players getting lost quest lines due to higher level players pushing them through the game could result in a post like this.
Futhermore, in my honest opinion, newer players told to use CoO and Xaveria for leveling before reaching DDC or DFR is another reason players get lost in the quest and quest lines. Sorry to get off topic a bit there ...
