I see there as an official building in the city of Transylvania and I feel that it could be something like an academy, which is why I wrote this story.

In the Transylvanian vampire academy, the night is falling and the students are arriving, to keep them safe a squad of soldiers, some on horseback, others on foot, guard the place.
During the day the same building serves as an art academy for non-vampires, who repeatedly meet the students at the beginning of the night.
In the place, the young people are guided to perform the tasks in a non-cruel way and not to frighten those who are taken as their victims, emphasizing that it must be a consensual act.
They are also taught to maintain a sympathetic attitude towards those who do not wish to belong to the gender and those who do not abide by the rule are severely punished with death.
They are tied on the roof of the building so that the sun takes care of disintegrating them, which is why there are some rebels around the town and there are also patrols of guardians of the law that look for them to apply the corresponding punishment.
The honor of being immortal is reserved for a few and it is only possible for a woman to give birth to a vampire if both parents are, which is why there are many marriages in which he or she ends up accepting to belong to the immortals.
The academy fulfills an important task for the town and the human inhabitants are grateful that it exists, since they feel safer and do not have to fear an impromptu attack by vampires.
Over time, vampires from other towns have joined the academy.
