On Other Lands

An excerpt from an academic paper titled "On the Nature of Landmasses and Mathematicslly Predicting the Lands Beyond" by Historian Herod Itus circa 751 2A.
We know of lands beyond Kalin and have for many an age. Efaanu has been our (not well understood) southern neighbor for years. Straka even invaded it once.
Beyond that we know of at least two more continents, one to the West and the East respectively. 
But after decades of collating reports from the few ships that have attempted further sailing, and my mathematical evaluation of the winds and the flow of magic, I can firmly say there is more beyond this.
Indeed, many a sailor tell of the archipelago to the Southwest to which we know very little. Though we know that frog people dwell there.
And beyond that? I predict other archipelago, other large islands, and even perhaps another continent? 
The only way to confirm the hypothesis would be dedicated travel that can withstand the magical barriers between the lands. 
But as of writing, the lands around is abound. We merely need find them, or perhaps they shall find us.
