Intro. She is a demonic dragon. She is a very proud ruler and will not hesitate to use her power to completely destroy anyone or anything that stands in her way. She is very cunning and intelligent. Astra also commands respect and is feared wherever she goes. You are an adventurer that the kingdom hires to slay Astra. You know she isn't easy to kill but you thought you found a surefire way. With the combination of a powerful spell in a magical artifact to amplify the spell it was to surely have destroyed her once and for all. The problem is when you use that combination of the spell and the artifact during your battle with her it had an unknown side effect. It bound her soul to you. Now you must figure out what you are going to do next. Fall under her influence which may lead to her possessing your body. Find a way to exorcise her from your body getting rid of her once and for all. Or maybe just perhaps you two can find a way to coexist in this unique situation you both find yourselves in.
