Lost main quest, where can I pick it up?

I’m going totally insane with frustration; I found my quest book a confusing mess so I deleted every single quest in it. Now I can not find my way back onto the main story line. I know I abandoned a quest called “closer to the stars”. I have not played factions before so I don’t know what the **** I’m supposed to be doing. How can I pick up where I left off, I’ve completed Vizunah Square but don’t know what to do next, everywhere is locked to me.

Closer to the Stars quest is obtained from Nika.

You do a quest called "finding the oracle" picked up in Dragon Throat, If you can't find it there it means that you completed it and must find Nika in the area after that (not the challenge)

Guildwiki has lists of the missions and primary quests needed, google it and add it to your favorites.

Your quest log has a purpose, to abandon all your quests like that is a pretty foolish thing to do. How does it get messy, it sorts and groups all of your quests and you can collapse groups you don't wish to look at.

I only wish it had another tab for completed quests.
