To whisk your armies through time and the skies, left-click the Vortex icon, and then left-click where you want your armies to appear. You must have <link="topic:line of sight">line of sight</link> to target this power. Your armies will fly up into the sky and drop down on the targeted spot. This power is very useful when you need all of your military might in one place - fast.
