Ive been wondering about this myself, and I already have these locations on record!I leave you with this Fun Fact: perhaps you have noticed, but in several of the dungeons in La Noscea you will find locations on your maps with names like "Llymlaen's Folly" or "Llymlaen's Trial." These are, in fact, sacred sites for the followers of the Navigator--each representing one of the 12 chapters in the tale of Llymlaen's Ascent. As part of their worship, followers risk their lives to perform yearly pilgrimages, visiting all twelve sites in the order they appear in the tale.
The chapters (in order) are as follows:
Llymlaen's Folly
Llymlaen's Flight
Llymlaen's Tempest
Llymlaen's Clarity
Llymlaen's Resolve
Llymlaen's Bearing
Llymlaen's Trial
Llymlaen's Encounter
Llymlaen's Stand
Llymlaen's Triumph
Llymlaen's Oath
