Sahaba was the child of the king and queen of somewhere. One day, she found the first human being to ever enter TLoG. They became best of friends. One day, the human died, and she got sad. Sahaba took her own life by collecting clovers in honor of the dead human. However, she soon died, and her essence was spread onto the first clover that ever sprouted in TLoG.
