The ProvHo seem popular, so here is another race for playtesters to try:
The Kontan Union: The Kontan were the Empire’s bankers up until the rebellion - confidence in the order was shaken and the Empire took steps to remove their power. With financial and trade contacts throughout the Galaxy the Union believe they are the natural choice to rule.
Special Powers: At the end of Phase I (after all players have collected Resources) you may exchange (trade) a resource - place a resource in the Pool and take your choice in return.
If you trade as a reserve fleet action you take 2 resources from the stock rather than 1.
Starting Forces: 1 Shipyard Marker 1 Home Sector Marker 1 Monument Marker 9 Fleets - 7 in the Reserve - 2 in the Home Sector 1 Technology Card (taken in reverse Play Order)
Design Notes This race needs no rule changes. The exchange power can only be used to swap resources in the pool - if no resource remain in the pool the power cannot be used.
