In Grotto, a new game coming to Switch later this year, you are the Soothsayer. People come to your cave, and ask you to say all kinds of sooths. Out of all of them, you are the only one that can read the future amongst stars and bones, and they need your help trying to figure out what will come to pass. You can tell them what you see... or you can withhold information for the greater good. Just don't be surprised if things go wrong.
The trailer is unhelpfully yet intriguingly vague, setting a creepy, mysterious tone but not exactly telling you what the game is about. Here's a small description from the developers:
Grotto is a mystical, narrative-focused experience. You are the Soothsayer. The one capable of talking with the stars and unveiling their messages. In a time of turmoil, the tribe of the valley turn to your powers of divination and come to you for guidance.
"Their fate will change according to your auguries," apparently, so you better be careful just what you predict, or you might accidentally kill everyone in the village. No pressure!
Grotto will be out on Switch towards the end of this year, some time between August and December.
