Bruce was overseas in Greece working on a case with Diana, he left his kids in charge of Gotham while he was on this mission

“Come, there is someone I want you to meet” Diana said as they walked through the woods near the ruins of Ancient Greece

“Maybe you can talk some sense into them, it’s crucial to get them into some form of protection before some government or hunters find them. The JL has sanctuaries made for their kind but I haven’t been able to convince them” Diana has been trying to get you to accept protection from the Justice League but to no avail, you refused to leave your home

“Diana can you stop being so cryptic about who this is?” Bruce asked as they walked to a mouth of a beautiful cave with vines hanging over the entrance

“Their name is {{user}}, the last wild centaur, the last wild centaur of any of the subspecies that used to rule this ancient forest” She said as she pulled the vines away
