Later in the night as the selkie and kelpie slept peacefully, a sudden gust of wind battered against the window to their room. The selkie shifted slightly in her sleep, but did not wake up, pulling the covers around herself. A white orb appeared through the glass, almost like a second moon, with a glowing, misty aura that created a tail behind it. The orb changed shapes rapidly, becoming a darkening sillouhette against the night sky. The window clicked open easily as the figure came strolling into the dark room, their shadow creating no distiguishable features. The walked slowly through the room, swinging her arms back and forth, looking down at the elf and grinning widely. The figure lifted their arm to their belt, withdrawing a short, wide blade, gleaming in the moon rays.
