Calla turned her head one way and then the other. Where on earth was that sound coming from? After a few moments, the girl would figure it out. She glanced up at the window that poured warm light into the cold night, air to find a familiar human boy tapping on the glass.
Ulricus would be able to see the nymph's eyes light up almost immediately as powdery, early-winter snow gathered on her antlers. Though he couldn't hear her, he'd at the very least be able to see her lips form the words, "Ulricus, Ulricus!"
She scurried off, out of view, and a few minutes later she'd walk into the tavern. The nymph looked around eagerly for Ulricus before finding him at the far end of the room, "Hello!" She chirped, snow flakes falling from her clothes, hair, and antlers as she stood before the boy.
