Ability: When an opponent builds a Dwelling (no matter where), gain 1 Power. 

Stronghold: As an Action, spend 6 Power to Transform a directly or indirectly adjacent unoccupied Terrain space (except Ice/Volcano) into your Home terrain for free and immediately place a Trading house there for free. This ability is not considered a Spade, but it counts as an Upgrading to a Trading house. You may take this Action multiple times per Action phase.
