Here is the guide to the Rank 36 quest:
1. Go to the back room of the Oak Atrium (Carpenter’s Guild). You will then be asked if you want to move out of the area. Answer “yes” and you will be taken to an instance.
2. Talk to Marcelloix. Accept the quest “Spanning the Spectrum.” You will then be taken out of the instance.
3. Go outside and head to the orchard. You will enter another instance.
4. Go though the dialog. That instance then fades and you are taken to another one. You also receive the recipe for a “fairweather fetish.”
5. Look around the instance for a “???”, examine it and receive a “large leaf.” Go to “requested items” > “quests” > “Spanning the Spectrum” and make the fetish.
6. Talk to the children. (When you talk to Powle you will give him the fetish you just made … didn’t seem like this had any effect on the storyline).Talk to Ryd and be taken to a third scene. NOTE: I don’t know if it makes any difference in what order you talk to the children. The aforementioned is what I did.
7. After going through the dialog you will leave the instance. At that point you will receive a “wood wailer petition.”
8. Talk to Nonolato at the Archer’s guild.
9. Go to Quarrymill to talk to Wybir. NOTE: Before talking to Wybir, switch to your adventuring class because you will have to defend him from some mobs, although the mobs are quite weak.
10. After defeating the mobs you will be teleported fairly close to Camp Bentbranch. Return to the Oak Atrium and talk to A’naidjaa.
11. Go to Mirror Lake. You will then enter a series of instances after which each one will give a journal update. Just follow what the journal says and you will eventually end up back in the Oak Atrium and given your reward.
