Intercepting the Mana Cells

I have devised a plan to acquire a power source strong enough for the creation of our portal.$B$BThe ethereal forces at Bash'ir Landing, atop the northwestern Blade's Edge Mountains, have been smuggling mana cells out of Tempest Keep and transporting them to the Sunwell for Kael'thas.$B$BThey have hidden the cells, but there is a way for you to find them; the ethereal carry phase devices that you can use to see the smuggled goods.$B$BJust beware the mana cells' phase wyrm guardians.
