Dave always thought as how does a heretic have near endless magic but after studying the Vampirism spell and with prodigy perk I figured it out.
They do not have endless magic it's just a huge energy which makes it seem endless as there is nothing endless in this world .
The immortality spell turns to the sun for new life which seems normal but if you study it you will understand that the spell draws energy from sun to keep a vampire alive so as they draw power from themselves they are actually indirectly drawing magic from sun itself and not just our sun if you study the runes used in this spell that represents sun its just a pure accident which created a loophole but this rune doesn't solely mean our sun but the meaning points to all star's in the universe like our sun and every other sun in the universe and there are trillions on sun's in the universe and all this large amount of energy which makes it seem endless magic .
So here is a loophole that you may ask if it represents all stars then why they don't get burned at night too from star light, but the answer is simple the intensity of UV light coming from Stars is not strong enough to harm a vampire it needs to be under direct sunlight. As if you see Moonlight is also sunlight reflected by moon and A UV shield prevents sunlight from causing harm to Vampires as told by Slater in Season.
Klaus's eyes lit up "So I can finally be free!?, Then what are we waiting for let's do it now Dave."
But Dave shook his head "Not now Niklaus. I need to prepare in case something goes wrong , We will Attempt it tomorrow."
As this topic finished Dave Decided this is the time When he can get Klaus to sign an Blood soul Oath which he improved after obtaining the Soul magic codex.
It binds the Both the parties to an Obligation when a party is unable to fulfil it they would face Terrible Consequences.
As when it comes to Dealing with Mikaelsons you can't be cautious enough so I decided to Use the Blood soul oath To keep Klaus in check.
As he throws a bait "Say Klaus you see after studying I also discovered something unique you're a hybrid so your blood can turn other's into hybrid too."
Klaus raised an eyebrow, intrigued. "You mean I could create more like myself?"
"Exactly," Dave replied, his tone measured. "But it comes with its own set of challenges. To transform someone into a hybrid, they first need to have werewolf lineage."
"What he can do that Everyone was shocked" and then Dave explained "Yes! As Klaus was a werewolf and after he was turned he became the first hybrid so in theory If he feeds his blood to a werewolf then kills it that werewolf will be reborn as a hybrid."
Dave grinned "So as previously Celene mentioned that She want's to be the same as Klaus, I can help her turn into a hybrid. What do you Think?"
Finn intervened "But Celene is not of werewolf Lineage how could she become a Hybrid."
Yes Kol and Everyone also asked the same question Dave Smiled.
"Oh yes she Is not of a werewolf lineage but I Have a way to Turn her into one."
As I Turned to Klaus "But the question is What price You're willing to pay. You have two options one turn Celene into a normal vampire or Turn her into a hybrid like you."
Klaus was in a dilemma, weighing the choice of what to turn Celene into. After a brief moment of contemplation, he made his decision. "I'll turn her into a hybrid," he declared, his voice steady.
With the choice made, Klaus turned to Dave, curiosity mingled with apprehension. "What's the price?"
Dave met his gaze, his expression serious. "Since Celene isn't a werewolf, I'll need to first turn her into one. That involves a dark magic spell, and there are consequences to using such magic."
Klaus frowned, sensing the weight of Dave's words. "And what are those consequences?"
"As your friend and for Rebekah's sake," Dave continued, "I'm willing to face whatever consequences come my way. They won't be much for immortals like us, but I won't do it for free. You'll have to offer something in exchange."
Klaus raised an eyebrow, considering the implications. "So, you're saying there's no real risk involved for you?"
"No there is a price but it's minimal when it comes to us being immortals and all." Dave replied confidently.
Celene "No need to pay the price Klaus I will be fine with not being a hybrid."
Klaus: "NO I want you to be same as me it's not for you I will do it for myself."
Klaus turned to Dave "I am willing to pay any price." said confidently.
Dave You will have to sign a blood soul oath with me.
Elijah "What is a blood soul oath you speak of."
Dave expalained the Oath as a spell that enforces that the other party keeps his words .
Dave then turned to Klaus "So what have you decided Take your time we are in No hurry about this we will decide this after we lift your curse tomorrow .
After we went back to our rooms Aurora approached me in my room and wished to turn Tristan into a vampire and her first sire, and Tristan was happy about it now So I have to create another batch of the daylight Tattoo Ink for him. I am sceptical of turning Tristan into an higher vampire a hybrid or an Original but then thought it's good enough for now we will see what happens as we progress we have thousands of years to decide.
