One time story?

[Dendritus-moon-guard (Dendritus)]

From an older forum post:

There is a mission table at the first populated area you come to when you get to the dragon isles (where all the trainers are). After your first toon has completed the story your alts can select an option at that table that opens up a lot of other options. It isn’t so much a skip as it is much less of a focus on the story quests.
