Prompt changing
They were not human they knew that, Ellie, Angel and Trina were Phoneix demons. Everytime they died they were reborn into different bodies. Same features, just different genders.
They had met the Originals when they were human they had found Henrik about to be eaten and had saved him, in doing so Ellie had been injured gravelly. Her face was badly scared over her eye, Henrik had been so guilty but it didn't matter they were happy he was alive.
But they were still turned into vampires anyway, and they had killed their friends. But what they didn't expect was their bodies to burst into flame.
The next time they had met was 500 years later this time as a brother and two sisters, Harry, Sarah and Angela. The family were delighted that their friends were still alive and well, but not how the remembered them, when they had explained that they couldn't stay dead they were relieved, it would mean that they wouldn't be forced to watch their friends age and die.
Sadly it was not to be, all three died when they tried to prevent Katerina from fleeing, they knew how much the ritual meant to Klaus and tried to help him.
It was with a heavy heart that they watched as their friends bodies burst into flame as disappeared once again.
Katrina escaped but not without bringing the wrath of the entire family down on her.
They wouldn't meet each other for another 500 years, this time in the company of the Salvatores who they had became friends with. This time they were three men.
Harrison, Hadrian and Charlus.
Klaus did the ritual with the help of his friends, they knew what sort of pain he was going through but no the pain that he was in.
After all they knew what it was like to be the only ones of your kind, but in doing so they had lost so much, Damon and Stefan hated them. Caroline wanted nothing to do with them, Elena despised their guts.
Not that they cared, they had helped a friend someone that they had been friends with for a 1000 years.
After all they would never betray the originals.
