Long ago this happened as well. A family of monster hunters came from the hidden pages of history and fought all the demons and monsters destroying them and their leader. The lord of the mysterious castle that changes every time it is revealed to the world. The name of that family was Belmont. They were human trained to fight any and all monsters and use weapons of any kind to do so. Sometimes others would help them but always normal people shubned and feared them. Driving them into seclusion.
One young magician was seeking the ruins of the belmont damily ancestral homes for weapons clues or magical artifacts when she finally found what she was looking for. A book of spells for destroying evil. She poured over it learning to control the elements and use energy to engage in magical combat tests of will and even destory monsters.
She lived in this place and practiced in solitude until one day the head and last remaining member of the belmint line returned. She felt his presence in the forest approching and quickly hides herself and all evidence of her residence. She used her magic to hide from him and watch him.
He mutters to himself alot a sign of extended isolation. He felt so strong even night creatures couldnt beat him phisically. He had two weapons a leather whip blessed and treated with anti evil properties and a silver clawed gauntlet with a grapple arrow and chain roll also blessed. She watched as the crest of his family was illuminated by the moonlight and he stepped into the doorway.
"Home sweet home. Someone has been here... many things are missing... but not the vault..." he said and he went over to the one thing she couldn't budge no matter what spell she used. A flat stone. Se heard words of power and the last one meant death and the stone vanished revealing a massive library.
Her gasp made him turn and fire his grapple at her without hesitation. He missed only barely and then she was revealed to him as her panic caused her illusion of a tree to fade. "Wait dont kill me im no creature. Im just a magician."
He walked over and slowly cranked the manual retraction as he did. "Its not wise to be sneaking around a monster killer in these times. I take it you were the one living here. You did well to hide the evidence but the cleanup is what gave you away."
He was close now and she saw his bearing was common his clothes were common his speech were outlandish but intelligible. His muscles were not seen but her ability to see energy patterns told her that he was incredibly strong. "You are welcome magician. And i thank you for protecting my new home. Even fixing it to be habitable. Something tells me youve journeyed as well."
She shook in excitement "yes until i came here. I was searching for ways to dight the night creatures demons and monsters that plague this land. Your family are a legend to the occult community so i searched all the holds i could find until i came here."
He lowered his guard and stowed his weapons. "You mist have found something to keep you hefe ling enough to fix the place and something tells me it was a magic book. You can keep it im only here for rest from my travels and to prepare for an assault on the monsters. You may even live here if you wish. Youve veen very helpful and kind."
He spoke softer now and her eyes drift to the open repository under the stone. He followed her gaze. "You want to see thise books i expect." He said and she nodded he offered her his hand. "Come on then as a resident you are allowed to learn the secret passwords and read to your hearts content."
Her heart soars and when she touched his hand she saw that fate had guided them to be together. In more ways than just meeting and living together. He didnt notice such a thing and as he guided her to the library she learned how to open and close the stone cover.
Inside was filled with books beastiaries diaries journals and cases with examples weapons and cadavers for education of anatomy. She was overwhelmed by everything and he was too careful with her. Months pass as he rests researches and practices with weapons and she poured over the volumes gathering much magical knowledge. She grew powerful wothout realizing it and he was searching for a special weapon. "Its called the Vampire Killer. Its a weapon used by my family and is effective on all creatures of evil but especially on the vampire lord that dwells and controls the creatures from the castle." She knew the legends but only legends.
Together thwy search and from time to time ocer the months night creatures would come and thwy would be slain by the pair as they learn to work together.
