"Possible priority point two.  Seemingly basic features of this world, including the method we are using to communicate, show signs of bizarre strong optimization according to no fitness function we are able to deduce.  Now that we've contacted you, it seems possible though unlikely that a very strange thing will happen during dath ilan's next lunar eclipse.  Everyone nearing or after their twelfth birthday should completely fast for two days before dath ilan's next lunar eclipse, just in case.  We think astronomical timelines should be synchronized between our worlds, but if we're wrong and that's immediately about to happen on your side, it constitutes a massive planetary emergency for you."
