After hours of searching with upper-class members of ryzom and endless searching on forums,.. It has been brought to our attention that the quest 'secrets of Silan #2' can be completed but not with the specified items. You can finish it with the yelp mushrooms instead of the fine zun amber. Fine zun amber is available here BUT it is NOT available in a quality of 15 or more. Hope this helps future players.
EDIT: there actually is zun amber!! it is north of the throne room!! what a find. its next to a mushroom apparently. ;)
