She looked at the many realms that spread out before her until she found the one she needed to find. Her mind running the possible scenarios on how to deal with this situation. She even felt a bit surprised when one of her minions told her that a way to the dimension of the dead has been opened. Only to close again shortly after. It was her dimension. Her kingdom. Her empire. So she started to seek out the magic that made the breach. Lucky for her there was faint linger of it left. It seemed familiar. She was certainly powerful enough to track it. So she did, to the mortal plain of existence it led her. One of her favourites of all. She was death itself, the harvester of souls, and she would not tolerate this insult. She followed the trail to a mountain. Known in the common tongue as Mount Everest. She saw the temple inside the mountain and focused on the souls within. Death guess seemed to be correct. It was indeed The Ancient One that had opened the dimension of the dead. She always had the power within her to do so, yet she became curious as to why she would go to such lengths. Powerful as she was, even for The Ancient One it was no simple task to break the barrier between this world and that certain dimension. Mistress Death had made sure that her realm was as good as untouchable. She noticed a soul next to The Ancient One. How curious, he possesses incredible power within him, yet seems unable to use it. She watched in amusement as she heard the man begging The Ancient One to teach him. She took interest in him, this certainly could get interesting. A faint smile appeared on her skeleton face. Perhaps this individual could be used for her plan. "Stephen Strange, I will be watching you."
She returned to the world of the dead, proceeded further into the dimension. The next part of her plan needed to be set in motion. She wandered the endless fields, walking among the souls. The dead fuelled her. They gave her power, but it was not enough. She needed more, so much more. There, the one she has been searching for. An ancient and powerful being, killed in events from the past. This time he would succeed, she would bring him back to life. She began focusing her power on the soul to make his body whole once again, trapping the soul within it.
"Rise and shine. You have much work to do."
She heard him breathing his first breaths. His eyes opened wide with shock when he realised what happened. Still laying on his back he turned his head to Death.
"Mistress.." He gasped. "Why have you brought me back?"
"I have need of you. You will go forth in my name."
She used her power to bring herself and her companion to the earthly realm.
Upon arrival he looked around him with even more confusion.
"What are we doing here? on earth of all places, what is the meaning of this?"
She placed her hand on his cheek and saw his eyes shut as her power filed his body.
"I need you to do what I want you to do. I need more souls, you must gather them for me."
She removed her hand. He was back. Powerful and burning with the desire to please her.
"What do want me to do Mistress?"
Ever since he fell in love with her, she was always able to bend him to her will. This time would be no different.
"Thanos my dear, I need you to find something for me. Seek and find all of the Infinity Stones and use their power to destroy all in my name."
He chuckled. "As you wish. It would be my pleasure."
Death smiled in amusement as she manifested herself back in the realm of the dead.
"Time to begin."
