Leah struggled to grip at Miranda’s mane, her stomach lurching at the sudden speed. She felt Miranda’s back sink unnaturally beneath her, the shifting water wrapping around her wrists and legs to ensure that she wasn’t shaken off as the kelpie accelerated to the speed of a landragon. The landscape blurred around her into an impossible swirl of colours, until Leah had to close her eyes against the fizzling brightness of it all. She really didn’t want to throw up on a kelpie.
When Miranda finally slowed, the sun had moved barely a finger through the sky. “Is this the city?” Miranda asked, moving the water that made up their form enough to push up Leah to see over their head. Sure enough, they were facing a high wall, carved with the sigils of a protective circle, each curving letter taller than Leah was. Leah looked back over her shoulder to see the hills she’d come from rising up behind her, the mountains beyond them already distant. She heard a bang and looked back to see that the guards on the wall ahead had noticed her, and were starting to shoot at her. The wall was high, but not high enough to be Caisteal Dubh—standing in front of it, Leah could still see the sky beyond.
“This isn’t it, keep going!” Leah called, ducking down behind Miranda’s head. She heard several splashes as bullets hit Miranda, though they didn’t seem to do anything. “Do you have to follow the river or can you go around?”
“I can go around,” Miranda said, and in a rush of speed the town was now behind them, the river still flowing on ahead. “How will I know which one it is?”
“I’ll know,” Leah promised. “Just… don’t stop close enough for them to see us at the next one, okay?”
“Why not?” Miranda asked, sounding genuinely curious. “Why did they throw metal at us?”
“They wanted us to go away,” Leah explains. “It didn’t really do anything to you, but that metal could kill me. I’d rather it didn’t.”
“Oh, yes, that would be no good,” Miranda murmured. “Alright, further away next time. Hang on!”
And away they went again. Leah instinctively tried to bury her face in Miranda’s mane, and then quickly turned her head to the side when she started to sink in to what was, at the end of the day, water. Miranda was a newborn kelpie, and seemed to have some portion of their mother’s knowledge of mortal creatures, but Leah didn’t know for sure if that included an awareness of what drowning was or why it was bad, and she didn’t want to chance it.
It's fun writing Miranda the kelpie. She does not, in fact, understand why Leah does not simply breathe the water.
