Well, on the globe pictured at some point in Awakening, the northern continent does resemble Magvel, from what we can see.
The southern continent could also be Tellius, from a certain angle as well; and there might just be Elibe on the other side of it.
That said it ends up looking pretty small with all those on there like that, and if they wanted to make more continents, well, they kind of shoehorned themselves into putting it on another world.
I kind of prefer Dragon's Gate being a dimensional portal between worlds with different continental masses, and being easily enough traveled through. --- Even so I will... I will believe! I will believe in the me, that believes in us, humans and the future! The drill is my soul!
