Arona Daal is an alien tradesman, once revered as the greatest station administrator in history. He is your first organic contact upon taking up the job as station supervisor. Through all your missions, he comes to you with goods to sell. Being so well-connected, Arona can send and receive goods directly with your pattern buffer, having no need for a star dock. It is hinted that he is responsible for continually getting you one contract after another, starting with the Groulien Workers Party. This is evident in how he keeps setting himself up to be your first trading partner.
Arona is very shrewd when it comes to trade. He buys low and sells high on everything, and always happens to have the one thing that any struggling station administrator requires. It is almost as though he can sense when people are in need of something, but that would be silly, right?
