Scabbard from wild plum

Four brothers. Four destinies. Unlucky number. One chose the path of the caster to soar in heaven like a bird and know all the secrets of being. Another was forced to accept a family business and become a support for parents and younger brothers. The third, talented in the sciences, always wanted to achieve a high position in society, but was not able to forget about the duty to the family. The fourth decided to become a monk to find a cure for all diseases.
All brothers will bring together the tragic death of one of them. Everyone will torment guilt, a desire to find out the truth and achieve justice. And the secrets of the past, where the clans of the spells ruled and there was a terrible tragedy that turned the world, are already ready to knock on the door to the brothers
