Re: World of Whorecraft: The Chronicles of Alexstrasza
There's a cave near the crashed airship, you have to backtrack a bit and keep to the left of the path to find it. There's a glowing crystal inside.
Then you have to get past the wolf inside, you need a dead fish from the walrus guys, a potion from the alliance camp, and some grave moss which is on the other side of the giant log at the far end of the area where the crashed ship is.
After that, and this is what stumped me for the longest time, you have to combine the weed with the note you got earlier to make a blunt.
