Tiaral

Well, the Jarls are looking for unoccupied territories, so why shouldn't we try too...

I might be wrong, but I have the impression that they are more interested in a more complete picture of the world than in lands for potential colonies. In any case, Revan has already said that we will sail to Encleasia and be captured by Theria. And then, upon learning about Thiaral, he will think, "Cool, a continent named after me. I need to conquer it!".
