When the Prince returned to the entrance of the cave drenched by the snow, he paused, finding Reina beside the fire. She looked bored, playing with the chard wood, muttering away at her new arch enemy.
"Big dummy! Baka! How dare he leave me behind. Ren is strong. Hmph. Just because he got tall, he think he can bully Ren? Mega Ultra Stupid Dummy. Punch to the nuts! Big Head! Stupid face! Ren will kick his ass one day!"
A rare, genuine smile branded the boy's lips as he watched her shadowbox the air. He coughed into his palm, making his presence known. Renia practically leaped up like a startled cat, mechanically turning her head to him, and trembled.
"A-A-Altair?! W~w~when did you get back?" Ren stammered with a wry laugh and glanced around suspiciously, unsure if he saw her messing around. She patted to the seat near the fire a little eagerly. " Have a seat. You're all wet with snow. Come get warm."
Presence/Authority comes from Charisma/Wisdom. And most creatures in this dungeon never had a Charisma above Five.
