What do you mean, how? [Anders tucks the note with the numbers on it away in his belt pouch, deciding he'll take a look at it again a little later.] They just... haven't.

[He shrugs loosely.] Maybe ships can't go that far, I don't know, I don't know much of sea voyages. Maker knows if there's even much else out there, or how far away it is.

Why does it matter anyway? Are you saying you know everything in your world?
