Quintessence

The emperor of Ceonus orders Kallea to create a youth serum. By order of the emperor, Kallea works on developing the youth serum he requested, but she needs a final vital component that she must find on another world. Kallea takes her small spaceship to visit the planets the gods have pointed out to search for the flower needed to complete the formula of the youth serum. When she finally locates the plant on a world called Xonarius, she is hardly prepared for the events that follow her discovery.
Or to find a captured dragon far below the surface.
