crossover fanfic (mortal instruments/the walking dead)

the main character of this particular fanfic is a young shadowhunter named Serena. she's 20 years old with hair like liquid silver. eyes the color like the night sky with golden flecks like stars. weapon of choice was a Naginata and a pair of sai blades. the reason they are like this is because her mother was one of valentine's firsts to attempt a better shadowhunter. she was shadowhunter with both demon and angel blood. making her like a half warlock half shadowhunter. she had befriended Alec when they were living in iridis. his parents took her in after her family was killed in the uprising. when the dead started to reanimate not in the vampire way Serena was cool and collected like most shadowhunters are. but she along with Clary jace Izzy Simon Alec and magnus fled new York by random magnus chose a portal to send us to Atlanta Georgia. these idiot corpses couldn't see them with glamour runes. we only use it when absolutely necessary. we liked killing them kept us practiced.
