This is a harvesting quest that sends you around the Isle of Mara and into the Mystic Woods to help restock supplies. Click on the Desk next to the Supply Cupboard at -94.21, 3.49, 104.75 to receive this quest.
10 Barnacles: The Mystic Lake, Mystic Woods (use climbing wall at 33, -37, 58 & along the water line)
10 Tufts of Beaver Fur: The Mystic Lake, Mystic Woods 124, -38, 68 - they look like shinies.
Even the Mystic Woods portions of this should be safe for crafters who are low-level adventurers, apart from on PVP servers where it is unlimited. For the Barnacles, the Tomb Protectors have a very small agro range. Stay along the water's edge and you should be safe - the barnacles have a pretty fast respawn time. With the Kindling, either dodge the aggro pirates, or stay in the Mystic Guardians area (neutral as long as you haven't killed any) and maybe have to wait a bit on respawn.
When done, remember to head back to the Far Seas building in Mara and turn in the quest at the armoire.
