Where are my troops dispatched to the Emporium?

Offensive Units sent to сapture the Emporium and Defensive Units that return with the Resources from it are sent directly to the owner's Acropolis.

In case the Emporium becomes vacant or disappears before the Attack, Scout Mission or Reinforcement reaches it, the Units sent to it do not travel back to their owner's City but are immediately sent to the owner's Acropolis.
