The fighting is finally over, but peace is its own kind of battle. Catra knows that a reckoning is coming, and she deserves it. She ruined the lives of most of the members of the Princess Alliance in one way or another, so they're definitely going to lock her in prison and throw away the key. Right? Adora doesn't think she's ever truly known peace, but with Catra by her side nothing really seems all that scary anymore. She isn't even worried about where She-Ra fits into an Etheria that isn't at war, or how she can make herself useful. Definitely not. While carefully navigating their new relationship, Catra and Adora find something lost and forgotten deep underground in an ancient First Ones ruin. The revelations that follow have implications not just for Catra, but for all Etheria. But distractions have consequences. Something evil stirs in the depths where no-one dares venture, unnoticed and unchecked, that has other plans for She-Ra and her allies. A story about love, purpose, and the sacrifices they demand.
