lumberjack narvis' other quest (and i do recommend you do them in this order, altho you are not required to do so - but it does save a run back to sable shores......) is a delivery of elm construction timbers to bristugo's master builder, builder tirrish. don't worry - you don't have to make the timbers, you just have to carry them to bristugo (if you haven't attuned to bristugo or made it your home shrine).
if you aren't already at the wws, get to it and approach narvis (notice the ! above his head, as you know indicating an available quest). when you greet him, if you have already done the 'behind' quest, you will notice that it is not available. listen to his tale and check your quest journal for details - and check your inventory for the goods! sometimes, there is a lag before the goods getting loaded to your inventory, and if you take off for bristugo before that, the quest malfunctions and you lose it for the day.
once you are sure you are ready, head to brist. i can recall, but if you can't, you can just retrace your path back on the roads you used to get to sable shores. anyway, once there (assuming you recalled - if you have to, start at the shrine), you will find builder tirrish down the right (west) fork of the main road leading to the portal pads., at the foot of the hill where the fort sits. if you don't see the ? over his head, the quest is borked. greet him to deliver the timbers and get your reward (obviously, since there is no real work required on your part, the reward is substantially less than narvis' crafting quest).
when next we meet, we will explore an example of an adventure quest, as a start to an exploration of a subset of such types of quest. more about that soon!
