I believe once you get to 70-ish, the Rorazan zone has quests that start opening up, but none of them are the main questline.
Of course, without running all the way to Tergothen Bay, there's a LOT of grinding to get to that level to be able to have the quests open up. Those quests are only 1-2 per area in the zone, not enough to keep up the level requirements.
You're better off just running the quests. By the time you get around the Fireboot Fortress area the quests start giving 750,000~1,000,000 XP per turn in, so you'll get through in no time. You might also try and get someone to help you with some quests in Atoulia Volcano. There are some easy quests there that have you running NPC errands without killing anything, and there are some quests that have you kill stuff, but if you're properly geared and avoid aggroing as much as possible you'll do fine. Running some quests in AV means you'll get a boost in the Dalanis area with XP so you'll stay on track.
The benefit of the Morrok/Toni questline is the fact that the quests are a lot of "go here and tell this guy this" and "listen to us talk out our strategy for getting this and this done", there's no real effort of killing many monsters or doing difficult quests. If you know the NPC and most quests will tell you who you need to talk to or the object you need to activate. Just make sure you do all the quests in the zone that are available to you from start to finish. If you don't, it's easy to lose the quest line and you'll spend a fair amount of time trying to find it.
Also, keep in mind:
Dalanis, Thunderhoof Hills is meant for 55-57
Southern Janost Forest is meant for 55-57
Northern Janost Forest is meant for 57-60
Limo Desert is meant for 60-62
Land of Malevolence is meant for 63-65
Redhill Mountains is meant for 66-67
Tergothen Bay is meant for 68-70
If you're not these levels then you may miss quests outside of the main Morrok questline. For example, I'm in Kampel Town on my Mage at level 62 and Morrok is waiting for me all the way down my Grafu. Not good, means I have grinding dailies to do to get to mid-63 before I should go see him. Somehow I'm missing some XP.
At the end of TB you'll get a quest to go to Rorazan.
