Their song

Choose the song they carry.

Their own song is already chosen. Tap any song to listen, or pick another to swap it. Every song carries a gift: courage, calm, curiosity or trust. It becomes their strength, and it decides who they are when the solar storm comes.

Last step

This cannot be undone.

You chose
