Enera knew she was gonna be in biiiiiiig trouble if anybody found out she came this far, but she was bored and she wanted to see something new. She wanted to be out before her friends; she didn't know why that was important to her, but for some reason it was. It must have been the boredom talking.
Sneaking out was easier than she expected it to be. @Rhaegara was used to Enera wandering about playing, and she hadn't run into anyone else as she sneaked toward the place everyone's smell was the strongest. Beyond that... the unknown. It was as though there was some invisible line holding her in, warning her back. For a moment, she nearly turned around, went back to the safety of Mama and her friends and the familiar.
But she'd come this far, hadn't she? If any of the grown ups discovered she'd even come close to the Other, she wouldn't be able to again. Mama would keep a close eye on her. She wanted to see it at least once before she got in trouble. She hoped it would be worth it.
