Chapter 1

Death of a World, Birth of a Princess

Harriet Potter was looking around while she sat on top of one of the highest mountains on Earth. Once upon a time, Earth was a beautiful planet with many plants, a blue sky and clear water. She could remember the beautiful days. She had had a great life with her friends. Hermione and Ron had married and had two children, living a long and happy life. Teddy had grown up without knowing his parents but he had built his own family. The Magical World had been peaceful after the war. Life had been wonderful for Harriet. She had been free. Like everything in her life, it hadn't lasted long. She was twenty when she realized she wasn't aging. It had taken her only one year to learn being Master of the Deathly Hallows wasn't something she could just get rid of. She was Mistress of Death, living forever beside death. She had watched her friends grow old and die. Life went on and the world changed around her.

Harriet had watched the muggles fight for silly reasons, killing nature without any care. Technology grew while nature died slowly. The muggles had tarnished their water reserves, making them undrinkable. Harriet had watched how the muggles killed earth. First magic left the world. Harriet was glad none of her friends saw this. Later animals had begun to die. Humans had died last, suffering from lack of oxygen, water and food. It wasn't a pretty sight but there was nothing she could have done.

Now, Harriet was looking over a dead planet. The sky wasn't blue, the ground wasn't green and the water was gone. She was alone. She didn't feel like that when Hermione and Ron had died. She knew someday they would die, she was ready for this but she never thought the world would die. For the past ten years she had been living in a dead world.

"If it isn't my little frowning mistress. You will get wrinkles."

Harriet looked at Death. He was sitting beside her. "You know I will never age so I can frown without any consequences. What is your new plan?" With time Death grew on her. He was a great friend and she knew him the best like he knew her the best. Harriet believed he found a solution for their little problem. Ten years sitting on a dead planet wasn't fun for him so he was trying to find a way to leave this planet.

"It's time for you to be born as your true form."

Her true form! Death had told her this but in the past she hadn't been ready for that. She loved Earth too much to leave. Now she didn't have anything in this world, literally. Her friends were long gone. She will be born as the Goddess of death in the God and Goddess kingdom, Asgard.

Frigga was watching her sons train with their friends, the warriors three and Lady Sif. Thor and Loki were so different from each other like sun and moon. Thor was the brave and loud one while Loki was the cunning and silent one. They complemented each other, destroying each other's weaknesses but unfortunately they didn't see this. They were strong together. When her husband Odin had brought Loki, he hadn't been sure about adopting Loki. Frigga never regretted her decision. Loki was a great son; she loved with all of her heart. They were now one hundred years old, finally adults in the eyes of Asgard. She was proud of them.

Frigga sighed, watching them made her remember sad memories. She had always dreamed of having many children with Odin. Sadly after trying so hard, they had only one child and healers had said she was barren after the hard labor. Hearing she will never have another child, had crushed her world. Odin had been a great support. He hadn't cared she was barren. She hadn't believed she could have loved her husband more but Odin had showed her it had been possible. Every night she had prayed to Mother Nature to give her a second child so she could make Odin happy. He always wanted to have a daughter. Maybe it was the reason she had chosen to adopt Loki without thinking. She wanted to have another child too.

"My queen!"

The voice startled Frigga. She didn't hear someone coming. She smiled gently, erasing her sad look. "Yes!" He was Odin's guard.

"King Odin wants to see you!"

"I am coming!" She threw a last glance to her sons. They were watching Sif and Fandral's fight. Sif was a great woman, worthy of her son. She knew Sif's feelings for Thor but Thor wasn't mature yet. Feeling dizzy, her body froze in her place. She felt sick. The world was spinning around her.

"My queen, are you alright? My queen!" the guard shouted, catching her before she hit the ground. Frigga didn't see her sons running towards her. Her vision went black.

She didn't know how much time past but Frigga was in her bed and the sky was dark when she woke up. She wasn't feeling sick anymore. She could hear her husband talking with someone from beside the bed. Most likely a healer. As goddess and god they were rarely sick.

"Odin!" Frigga whispered. Odin was in her side immediately holding her hand gently.

"Yes love!"

"What happen?" Frigga asked fearfully. She didn't want to die.

"Our ancestors, the Gods decided to bless us my love! You are pregnant!" Odin said smiling at her lovingly. Something had died in his heart when he had heard his wife collapse. Now, they were having a miracle. A baby! He knew how much his wife wanted another child. She thought she was hiding from him but Odin knew her the best.

Frigga touched her stomach gently. A child! Their baby was inside of her stomach. Impossible! She was barren, the healers had said this. She saw love and happiness in Odin's eyes. He was telling the truth. She was really pregnant. She couldn't believe she was pregnant again. The news was so unbelievable. She didn't realize she was crying until Odin wiped her tears.

"Don't cry my love! Today is joyful day!"

"We should thank the Fates for this miracle." Frigga said, wanting to show how grateful she was.

"A feast will be held in their names."

Nine months passed without any problem. Frigga's pregnancy was going well. The healers couldn't find out how she became pregnant. She was still barren but she didn't care. The Fates blessed her with this child and it was all she cared. She was careful about everything she did. Even Odin and Thor were acting like headless chickens when they saw her walking in the garden or lifting something. Loki was too quiet. He didn't say anything about pregnancy and he was ignoring her. Frigga knew he didn't like having another sibling but she believed he will love his sibling in time, she hoped.

She stroked her stomach. She was still in a dream world. The healer couldn't see the gender, the baby wasn't showing them. She hoped it was a girl. Odin always wanted a daughter. His line never had girls so it was mostly a boy but she prayed it would be a girl.

"It's time my queen!" the healer said. They decided to remove the baby today because her body wasn't strong enough to have a normal birth. She was scared. What if something went wrong? "Everything will be fine!" the healer added after seeing her panic.

Frigga lay on the bed in the surgery room. They gave her a potion, which let her stay conscious while preventing her from feeling any pain. She watched them cut her stomach open, taking her baby out. One healer was looking at her baby while others healed her. She wanted to see her baby, making sure it was alright.

"You have a healthy baby girl my queen!" A nurse helped Frigga to sitting position. She held her daughter in her arms for the first time. She had gold hair like herself and Thor, her skin was pale and she had emerald green eyes. She was going to be a beautiful woman. "Call the All-father!" she ordered. He needed to see his beautiful daughter.

Frigga didn't take her eyes away from her daughter until she felt Odin's presence. He sat beside her. "We have a daughter!" she said, smiling happily.

Odin touched the baby's cheek. "She is beautiful." He could feel a great power from his daughter. Odin also felt His presence. His power was hugging her like a cloak. So he finally chose a master. "She is the Goddess of Death."

"Eostre! Her name should be Eostre!" Frigga spoke without taking her eyes from her. It was a fitting name for the Goddess of Death.

"Resurrection Day?"

"Also it means spring. The season nature comes back to life. After all death is the beginning of a new life."

"A fitting name for the goddess of death!" Odin agreed with his wife. He loved his sons but he always wished to have a daughter like his ancestors. Now he was holding his little girl. He couldn't be happier.
