Requiem of the Undying

Arzno, the City of Heroes, fight a war against an enemy they could not hope to beat, the Vampire Menace of Mexico. For over 150 years, they have survived in a place no one thought they could. For over 150 years they have fought against the monsters of the night, and protected those who could not protect themselves. 

An Atlantean Princess travels to Arzno in search of finding help to rescue her kidnapped mother, who was dragged somewhere into the depths of Mexico. Unable to convince the young Princess her mother was beyond their help, the city sent a small group of warriors, mages, and psychics to escort her into the heart of Mexico. 

Unsure of what they'll find and encounter, the group prepares for anything.
