Pattern? What kind of pattern did you find?
It is not confirmed yet, so don't get your spirits excited, but it seems to aim for creatures related to the evolutionary relatives of sentient beings and those sentient beings too, with anything that they may have had an emotional attachment to. It is a zigzag type strategy, and doesn't always consume anyone in that niche either, so there may still be people around, frozen in time, even on this planet if not others too...
