the best advice I can give you is if your willing, look up the storyline for celestia and if you don't have the quest that your suppose to have at that moment then go to the person your suppose to get the quest from, or just put up the find a quest thing every where you go in celestia or just do all the side quest until one of them keeps going on
On that link, you can click on the highlighted items for more details, like 'who' gives the quest, where they are located, prequests or requirements, etc.
Wouldn't it be awesome if the main line quest in each world had a special badge or star or AnY significator, really Man, that would sure help....... Just saying
