Epimedé is an independent alter ego created by the infamous criminal of the past, the Lifeblood Witch Siez, to manage her abode Lifeblood Manor. Like all other alter egos born together, Epimedé was built in a way that they can judge themself and freely establish their own values without any behavioral restrictions. Then for some reason, Epimedé developed a particularly positive mindset pursuing peace, and altruistic personality to help in all actions that do not harm others. From time to time, they even hit the trail to assist other witches and people in the outside world if they had no more work to do inside the manor.
When some experienced hex-weavers who noticed Epimedé's origins captured and investigated them, they did not resist at all and kindly shared what they know. As it turns out that Epimedé is a completely harmless creature without any malevolent traps set inside, their amicable comportment began to be recognized in the general hex-weaver society as well, gaining reputations enough to get them an honorary title of 'Witch of Shapes'.
After Siez's disappearance, Epimedé is still managing the Lifeblood Manor with all the remnant servants, moreover sprucing up the manor with the gifts they get from various friends they made around the world.
