Ok, now you need to kill 10 a whirling maelstrom. You will find these around -386.16, 446.38, 354.28 . The item to update the quest is a body drop.
Return to Razim Othologold to complete the quest.
When you complete this quest, even before you turn it in, your fame will have spread throughout Quel'ule and many more persons will now want to speak with you!
Also, Razim mentions that if you should find any evidence that may further his research he would like you to bring it to him. This may be a hint for a future quest but, if it is, we have seen no evidence of further quests from this NPC.
