DAY-UM...history goes WAY WAY back.
Looks good.
Edit: This is a short draft I had written after we talked about Kallisti. Let me know what you think. I didnt get too deep because I wanted to adapt him to your history.
Kallisti Health was opened by an apothecary who focused on developing medicines in al' Khem.
After the formation of the Allied States, Kallisti, an apothecary, left and traveled the Cefnor Basin. He began his quest for creating a collection of recipes to create medicines. His infamous book was called, De Materia Medica (On Medical Material), published in 1787. It expanded into several volumes that he further published over his lifetime. The volumes covered a wide range of plant and animal material, their properties, proper preparations, uses, and recipes for medicines and poisons.
Al' Khem's liberal, and almost obligatory, use of a variety of medicines attracted Kallisti to move there and set up an apothecary shop. The shop funded his experiments at creating new medicines. He grew close to the locals and became involved with their protests and revolts.
Edit: Added a bit more.
Supplying the locals, during the protests and revolts, required increased production capability and raw materials. He acquired chemical factories, built larger laboratories, bought tracts of land, and modernized his medicine production in the process. His family continued ownership, and his legacy, creating a newborn pharmaceutical company. The diversity of Kallisti Health, able to create chemical materials, grow medicinal crops, create base medicinal materials, conduct research and development across various scientific fields, and of course, create drugs for various purposes, lead the name to be changed to Kallisti Group.
