Option C - Order Them To Leave

The visitors leave.

Problem solved.

Several months later, they return.

This time there are more ships.

And some of them are heavily armed.

Their leader says they still want peaceful trade.

But now there's an obvious threat behind the offer.

What do you do?

C1. Fight before even more ships arrive.

C2. Agree to trade, but only under strict rules.

C3. Ask neighboring kingdoms to form an alliance against the outsiders.
