You will come across a fight with some Voidwoken. From there, backtrack east and this time head Northwest. Have your elf eat the leg to start the quest 'Hide and Seek'. Put him out of his misery, open his body and then loot the leg.
When you come to multiple paths, take the southern one and you will come across a shark on land (x:465 y:-38). Head west from where you start on the beach.
