Medical Problems is a new adventure for The Witcher with two chapters. Each chapter is playable separately and can be understood without playing the other chapter, though of course they're at their best when played together and in order. Your choices have consequences, and which ending you get depends on the combination of choices. In the first chapter, Geralt helps Shani cure an illness that has a darker origin than she realizes. In the second chapter, Geralt must cure a special, created disease that's been specially formulated to overcome a witcher's usual immunity to disease, a disease that will kill Vesemir, Eskel, and Lambert unless Geralt can find the creator of the disease and force him or her to reverse it. Both chapters take place between the events of The Witcher and the events of The Witcher 2.
This three-part statue of the goddess Melitele stands in the center of the village of Riverford, where villagers pray to her, asking that Shani and Geralt figure out how to cure their sick friends and relatives.
