The Long Journey Home

The first requirement is for the Ilitza to be one of the races spawned in your universe. If they do, at some point an Ilitza ship will ask you to pay off their gambling debts for you and give you 500 credits, saying you can keep the change. Alas, it's too good to be true, as when you reach the target station, they will ask for 700 credits. If you pay the debt in full, the achievement unlocks. Make sure to have 700 credits before docking at the destination, as you get no opportunity to sell things in order to pay it off, and it won't pop if you don't pay in full. This also jumps you right to the Ilitza friendship rank, although it hurts your rep with the Cueddhaest if they're in your universe.
