Dread Our Coming, Suffer Our Presence, Embrace Our Glory (Solonavi War Cry)
Can you place a activation token in a hex that has an enemy token? I could not find anything in the rules saying you couldn't.
As Budgernaut says, only YOUR activation tokens affect your units' ability to move or to activate areas. So you can activate an area with an enemy token.
Also the rules say you can not move out of a hex with one of your activation tokens. So that means I can still move new units into the hex, just not out of it?
You cannot activate an area that has one of your own tokens already, so you wouldn't be able to use Mobilize or Conquer to move units into a hex with a previous activation token. However, you could use Strategize to move into a hex with your activation token (but could not move units that started in such areas out).
