I have no idea how to get into the labyrinth. I have a level 56 life wizard, and I can't get the rebirth spell because I can't do the quest. Any ideas? Please help. Thanks in advance.
I'm not sure how far you have gone in Dragonspyre, but we find that in this game, sometimes we get a quest (like the ones from our school professors) that will send us to an area that we have not opened yet by following the storyline.
It sounds like that is what happened to you here. If you continue to follow the main quests in the storyline, you will eventually go to The Labyrinth, and you can do the Main Quest and your Spell Quest at the same time.
In case you need more info, this link to one of the fansites shows all of the quests (main, side, crafting, etc.) in Dragonspyre:
