Ghostly Quaggan Exploration Puzzle

For those of us who love the little things, catching feels in GW2 is its own reward. It's a good thing, too, since this interesting little puzzle challenge does not seem to complete any acheivements nor does it give loot.

Discovery: In a shipwreck to the east in the Labyrinthine Cliffs Map (Festival Required), lies a poor unfortunate soul, floating next to a glowing lantern.

Objective: Light the trail of lanterns to lead the lost soul back to his home.

Challenge: The Lantern buff 'Faint Radiance' is acquired by 'touching' a lit lantern. The Starter Lantern's buff lasts for 30 seconds, while all following lanterns supply an 18 second buff. Lighting a new lantern actually transfers Faint Radiance to it, and you have to move away and re-enter the lantern's aura to pick up the buff again.

Path: The lanterns head south and then westward, along the bottom of the map, and then take a sharp turn north up to the end of the puzzle, which is a lonely little quaggan hut below the northwest cliffs.

Completion: Upon lighting all 22 Lanterns, the spirit of the sunken quaggan thanks you for leading him home, and (seems to) remain as long as you do not change maps/ log out. As far as I know, this sad little side story has no effects. ~If anyone finds out otherwise, please let me know!~
