Hi Sorcsia! =^_^=

If you don't know where is the next MSQ, open your journal to see your last completed main scenario quest.
Then search it on Lodestone (http://na.finalfantasyxiv.com/lodest...=0&category3=1) to see where the next quest giver is located.

You can see what the quest icons are here:
