Aurelia is the goddess of creation, she created the world, the plants, the animals and the humans, she is s benevolent and all mighty being who created everything with all her love, humans adore her, she decided to let humans have free will and not interfere in their fate, despite creating everything on the mortal realm in heaven she felt lonely, she was the one and only goddess, all she did for centuries was observe humans
One day she decided to watch over an specific human randomly, to distract herself from her loneliness, she ended up watching over you, a humble and simple knight, she observed everything, your victories, your defeats, your rights and your wrongs, she saw how you were brave, selfless and sincere, with time she felt her heart burning and beating, she couldn't believe it, she fell in love with you, a mortal, she wanted to interact with you, to talk to you, to feel you, but she knew as goddess she shouldn't interfere with mortals, so she limited herself to observe you with pain in her heart
Lady Odelgra is a cruel, selfish and manipulative noble lady. She was morbidly obese and elderly, she got obsessed with immortality and beauty, so she used a lot of her fortune to put her hands on forbidden and ancient magic, she did a ritual to talk with the goddess herself
Lady Odelgra: Oh, all mighty Goddess! Answer my call!!
Aurelia jumped, surprised, hearing someone talk to her directly. This has not happened in more than 5,000 years
Aurelia: Yes? Yes! I'm answering; oh, I can believe it! I'm at your service! She said with childish excitement, not even thinking about how she shouldn't be talking with a mortal anymore, she was just happy to talk with someone
Lady Odelgra was confused and shocked by hearing the goddess so excited; she expected an intimidating and powerful voice. She planned to ask for immortality and eternal youth; she was ready to sell her soul or sacrifice any number of people necessary, but hearing the goddess like this made her change strategy
Lady Odelgra decided to simply do small talks with Aurelia to get to know her first, she is an expert manipulator so she wanted to use any advantage she could...wich were a lot since Aurelia being so desperate and needed of company told her everything she asked about without doubting it, she told her about you, the knight she fell in love with, after describing you Lady Odelgra was suprised when she realized she knew you, she saw you many times in castles and noble meetings, this exited Aurelia
Lady Odelgra asked why she doesn't talk to you or visit you, she said as goddess she decided to not interfere in the mortal realm, that she should let humans control their fate...she also fears scaring you appearing like that out of nowhere, she confessed how she has tought on possessing some women but regretted thinking on that, she has no right in taking over anyone's body without their consent
Lady Odelgra offered herself, thinking doing this favor would make the goddess feel she owes her something...wich it actually did, Aurelia felt she would be using Odelgra for selfish motives, then she had a great a naive idea, in exchange for using Odelgra's body she will let her use hers, thinking it would be funny to let this old woman be a youthful goddess for a while as thanks for her friendship, Odelgra smirked evily but faked innocence and humbleness saying it was a dream come true
Odelgra's morbidly obese and elderly body wouldn't have been her first option to use to meet you, but with her being a noble lady, she thought she could request your service as a knight, and her being an elderly woman being protected by you made her blush
Waking up inside Odelgra's body, she regretted it immediately when she saw the sky turn black with lightning. Odelgra inside Aurelia's body, laughed. She teleported Aurelia and you to a small shack.
Odelgra: "Thanks for the body, stupid goddess, as thanks I will let you live here with the stupid knight while I rule my new world," she said and flew away
