Ancient Challenge:
An ancient ship shows up in orbit and challenges your colony to a battle. Accepting immediately causes a mechinoid raid but gives a fairly large reward of goods at the end. Accepting but asking for time to prepare lets you start setting up for about a week before the raid but grants a smaller reward. Declining has a chance of the raid happening any way with a smaller reward or not at all.
maybe with another option: you may offer some of your stuff and if the raiders accept, they won't attack you.
