"The great Tanith Low, slayer of vampires. Killer of zombies. Murderer of trolls. She can walk up walls and hang from the ceiling. She can swing a sword and end up slicing you in half. Supreme Overlord Tanith Low, dressed in her leathers and carrying a sheathed sword. Rides a motorbike like a maniac but still doesn't fall off. She's not afraid of heights or water or spiders. She's not afraid of anything, because she's Tanith Low. Oh, apart from the dark. Supremely Awesome Afraid-of-Nothing Tanith Low is scared of the dark."
"It's a perfectly logical fear," Tanith muttered, crossing her arms defensively.
Valkyrie raised an eyebrow.
