Duties of a Lionguard

Overview
Quest Summary: Obtained by: Lionguard Riddik in North Kryta Province (right in front of the entrance to Lion's Arch) Requirements: none Reward: Mission Text: "Let me ask you something. Do I look like someone with nothing better to do than stand here all day, every day? I didn't think so.
 * Look for Lionguard Orrin at Miraba's farm
 * 500 XP

So why is it you can tell that even tough we hardly know each other, but why that thoughtless Orrin, after all the years we've been friends, thinks it's perfectly fine to go gallivanting about when he is supposed to be here, guarding the gate!? I bet he's off trying to romance Miraba again, even though it's clear she wants nothing to do with him.

In fact, can you do me a favour and check? Her farm's just a short ways northwest of here."

Walkthrough
After exiting Lion's Arch go to the right (northeast) through the narrow valley and then left (northwest). It isn't very far, but there are quite a few Bog Skales in this area and you can easily be swarmed if you're not cautious (especially when henchmen are involved). In the rear you'll see some buildings. Talk to Miraba to finish the quest.
