Torkus has asked you to obtain an Unstable Flask of the Sorcerer for him. Return with it to him at Ogri'la atop the Blade's Edge Mountains.
As to that other magical flask, it can only be obtained from one spot: Bash'ir Landing. It's an ethereal base, and they aren't too friendly with outsiders, so it might be a little dangerous to obtain.
Where's Bash'ir Landing, you ask? Well, if you get on your flying steed and head north by northeast, well past Forge Camp: Wrath, you'll eventually spot it. The Bash'ir crystalforge itself is at the northeast corner of the landing.
Thank you for doing this, [player]. It'll mean the world to our sons!
