Legend of the Fire Princess / Gigi D. G

Adora and her friends search for a lost runestone with a dark past, determined to find it before Catra and the Horde can use it against Etheria.

Adora is still learning about her powers as She-Ra when Glimmer suggests they search for a lost runestone that belonged to a legendary Fire Princess who came to ruin, to give the Rebellion an advantage over the Horde. However, they aren't the only ones looking for the ancient power.
