fenrir greyback is searching for traces of someone around him, but the smell of blood from dead is preventing his smell sanse. Alex took out silver daggers and silver knives with chains, these are made from the silver given by system. he made them to deal with werewolves if he encounters trouble.
he watched fenrir greyback and remembered his ambitions from the movies, he disgusted when he saw greyback in movies. now he is standing before alex. Alex doesn't waste anytime and cast virtualis mundi ,the virtual world spell on greyback.
Greyback is knocked into a trance with that spell, then Alex cast imago on the silver knives and daggers with chains and coated with the direct concentrated wolfsbane herb dosage, which when unprocessed is toxic to werewolves, Alex used the levitation charm and oppungo jinx to move them towards the werewolf and greyback who is suffering in the virtual world didn't notice them.
the silver knives and daggers directly pierced greyback and bind him to a wall. greyback has awakened from the daze and screamed due to the pain, he wants to attack the assilant but can't do anything since he is now attached to a wall with silver chains that pierced his body.
he also noticed the poison in them and looked around screaming," please let me go, I will never mess with you, pl-please I don't want to die I will do anything, just don't kill me, I- I - I will be loyal to you, please don't kill me great one". Alex is smirking at his words, he didn't expect greyback to surrender that easily and said in a different voice altered with his magic," I will not kill you if you sign a magic contract with me, but beware one wrong step and you'll die from that, remember this well, you're not the one in control, it is me who will rule you, do you understand?". greyback said yes and Alex send the contract to him with conditions of absolute control over him and his followers and not even allowed the thoughts for a betrayal. after the conditions greyback gulped and thought ,"after I get out I will kill him , this just a contract not an unbreakable vow, only a fool will do something like this". little did he know the moment you accepted the contract with your magic, your body and soul will have seals on them and cannot break the contract, thinking about betrayal will make his body and soul experience a burning flame and doing the action will cause his soul to be erased. greyback who doesn't know this agreed and signed the contract using his magic and thought of his plans to kill, but experienced a burning pain in the soul that is where he had realised the contract power and cold sweat formed on his forehead, if the contract made by the person is that strong then how strong is can this person be? Alex motioned his hand and all the chains released greyback and returned to him. Alex cast imago on himself to look like a hooded figure and arrived infront of greyback.
he used magic again to alter his voice and said to greyback," let's go back and see your friend, shall we? ". greyback just nodded and said nothing he is trembling imagining the power of this wizard, Alex through the contract connection to Drusilla told her everything and asked her about the situation.
she reported that she captured Sanguini by blowing the blood in legs and arms and also said that she destroyed the whole ritual palce using magic. Alex praised her and went towards the basement , he warned greyback not to try anything funny through his connection and greyback is shocked by the voice, only Alex can freely talk through the connection, other end needs his permission to contact and talk back to him.
he arrived at the ritual room to find all the vampires kneeling infront of Drusilla and a Sanguini whose has no limbs. the other vampires drew their wands upon seeing the hooded figure and pointed towards Alex and Drusilla hurriedly said," don't, he is the one that saved me and helped me to gain more power, don't try anything to harm him unless you have a death wish". the vampires who heard this have surprised look on the dwarf hooded figure and thanked the person for the help and made a way. greyback followed with his head down like a good boy and Alex approached Drusilla , he told her everything and assigned greyback to Drusilla but said don't harm him as he will be a valuable asset in the future.
Alex told her that he is leaving because it is evening and he has a business to attend. she is disappointed that he is not participating in the celebration but didn't stop him. Alex before apparated gave her some instructions and also told her to write a letter to the ministry about the situation and also asked her exclude greyback from this. he also told greyback to be good boy with Drusilla and apparated away to the forest, he cannot apparate into Hogwarts, only his pheonix can do it, so he summoned Nile and told her to apparate him to the Room of requirement.
