From there, they journeyed up north on foot, through Abalathia's Spine and picking up people on the way, until they hit the Dravanian hinterlands, at which point he went 'okay, here's the plan: SECOND BOAT' which they use to sail to what is now Actual Sharlayan. It's possible that New Sharlayan was founded there in remembrance of his journey, but Nyunkrepf didn't build anything there except a way to get away from there.
