Shadow of Zero

Shadow of Zero by Mizuki_Stone (also available at Fanfiction.net) is a crossover fanfic between Dungeons and Dragons and Zero no Tsukaima.

Levethix’Moxt, serpent king in the guise of a drow, was on the wrong end of a manhunt when a green portal appeared before him and he decided to take possible death over guaranteed death.

Tropes applicable only to Shadow:

 * Knight of Cerebus:

Tropes applicable only to In the Shadow:

 * Large Ham: Lev is most definitely this, even lampshading the fact. “I’m a spontaneous spellcaster! Ham flows in my veins like blood!”
 * Suspiciously Specific Denial: Played with. Assuring someone that you don't want to eat them while not in the shape of a dragon might just be a bad idea, Lev
