Also, you still have to do the first part of the quest on each character. (Can't just pass the lantern around.)
However, you don't have to gather the items on that character, other than the silver sappling seed (on the human quest) which is on a 24 hour timer anyway. So you have to run down there for that, and again for each node.
You can repeat part one on your strongest character and farm orbs by removing it from your pack, bag of sending, giant beetle, hold it on cursor and last object macro etc etc. Or for the gargoyle quest that needs cherry blossom holding that on cursor and running towards it again will let more appear in your pack as well as the other means.
Atlantic reverted so I had to redo 6 characters x 3 nodes. Yesterday I had 2 Cloaks out of 12 nodes, today I have 0 out of 18, yay for reverts.
