It was only as he continued, Fancy seeing you here, that the girl's rationality caught up with her. Turning around, heart still thumping slightly from the adrenaline rushing through her system, she spied the oddly decorated unicorn she'd now bumped into on a handful of occasions, and smiled. "Hello Rixen. Do you know anything about this?" She inquired. Like her mother before her, Otem often forgot pleasantries and social niceties, like saying things such as, How are you Rixen. It's nice to see you again, etc,. Instead her mind had turned directly back to the veil of black that seemed to blockade the way forward.
