Grogu

Grogu is a child of Yoda's species who survived the fall of the Jedi Temple and spent years in hiding. Recovered by Din Djarin, he used the Force to heal and to defend them both, and was hunted by Moff Gideon for his blood. He trained briefly with Luke Skywalker, faced a seeing-stone trial with Ahsoka Tano nearby, then chose to return to Din Djarin, taking the name Din Grogu rather than remaining a Jedi.
