It has large and varied habitable areas and a very large population. Lose one turn immediately. No trades allowed this turn, one trade next turn, unlimited after that. The huge population makes it difficult to find the right contacts. The attacking species gets plus one to the die roll.

Draw one marker from the bonus cup and place in this system, regardless of where it's supposed to be placed. If it is a demand marker for a good this race doesn't buy, one of that good may be sold with that demand marker. With all the varied cultures here, you can find nearly anything. The purchase this turn may be made as if the IOU marker for this race was being turned in. With this many people, not everyone's going to know when a promise has been made, or kept.
