The girl had reached the Golden Core stage.
Vin wasn't surprised though. She indeed had something special about her. It was almost intimidating when one got too close.
Vin wouldn't be surprised even if Firey said she had reached the Nascent stage. She would only see her as a little genius.
"In that case, I'll lead you to the tower!" Vin then looked at Himmel Soan.
This man was Firey's guardian, so she thought she should tell him what was going to happen. "Are you alright with it?"
Himmel Soan nodded. He didn't know anything about the tower, so he was happy to have a guide.
Vin took Firey's hand and led her to the tower. The previous student happened to come out after lighting the third level. Firey could go in now.
Vin took Firey to the entrance of the tower and told her what to expect once she went inside. After gaining a rudimentary idea, she entered the tower.
Vin went back and stood by Himmel Soan's side.
