People needed to have appointments with the relevant personnel before they were given a special permission card to enter or leave the Sloan Castle.
The same goes for entering or leaving Sloan Peak but Ainsley could come here without any permission card because the barrier outside recognized her aura and immediately let her in.
Entering the barrier was easy for Ainsley, but when she faced the fence gate in front of the Sloan Castle, because she didn't tell her people that she returned today, she still had to ask the gatekeepers to open a small part of the gate for her.
Aside from the three cats, Ainsley also had Blaze, but because Blaze's size was too big and Blaze was trying to control the trick of reducing her body size just like other sacred beasts, the bird went to the forest around the Sloan Castle without Ainsley.
Anyway, Blaze could return to Sloan Castle anytime after contacting Axelle or other people.
