Well if you insist, then Abbadon will show up in year three. Still, he's the leader of the rest of the Darklings in their former universe, so if he tells them to attack the Imperium the minute they exit the portal, they will.

The Imperium messing around with trying to open a portal will likely weaken the barriers between universes enough to allow Iyoka, Glacier, and Krianus to open their own enough to summon Abbadon. After that we'll see about what happens with the rest of Abbadon's followers.
