What happens is a crude plan that's simple but effective. Luke chats up quite a few people about Heba, Tian, and then the magic system affiliated with Tian. Considering his newfound connection to Tian it only makes sense.

After that, it's simply a matter of persuading some of the rebels to take him on a tour of the mage's sector. After securing a promise of introduction to a great trainer. Why would he pass up such a kind offer?

He can't! That would be rude.

And so, just like that, Luke leaves with a few of the natives. Because it seems like the safest option.

You won't beat him that easily!
