The Last Gasp of Y'Shaarj

I got this today in LFR Siege of Orgrimmar. October 22, 2013. Whatever you do, DON'T leave without turning this in. You can only turn it in RIGHT AFTER you kill Garrosh, can't just give it to Loremaster Cho anytime during the raid.

Edit; you don't really kill Garrosh but he is unconscious, as his health bar says. But you can use [item=90175] and [item=88589] on his body, technically killing him though!

Edit #2: How embarrassing, forgot to say KILL Garrosh.

If you soloed this raid on mythic difficulty (mythic SoO = what was called heroic SoO during MoP), and at the end stood there wondering how exactly you're meant to get back to the Inner Sanctum from Stormwind, in order to turn in the quest to Lorewalker Cho... then maybe you're like me, and Garrosh just happened to fall right on top of the portal that can take you back to the Inner Sanctum. This happened to me, and so Garrosh had obscured the portal-- so I had no idea that there was a portal and just kept running around trying to figure out how to get back. If you also can't see a portal anywhere, try hovering your cursor over Garrosh-- and eventually you will see a speech bubble (ie, your cursor will be over where the portal is, which is obscured by Garrosh). Click that and you will be transported back.

If your raid leader is not a nice guy and destroy raid after killing Garrosh(or if you just leave), you will not be able to finish quest if you get away from instance as all NPC despawn (I go back to raid, and whole room was empty).
