Under the spell of dark magic from a fallen star, the dark elf king and queen of the kingdom of Daibazaal, Zarkon and Honerva, have declared war on the world, leading to the genocide of their former allies of Altea, the light elves. Only their princess, Allura, possessing their ancestral magic, remains to stop them - a feat she can only accomplish with the help of her human allies of various kingdoms and the unlikely aid of the elusive and ostracized half-dark elf prince, Lotor. Helping her strengthen her powers and providing vital intelligence, he becomes an essential ally to her and the resistance, but his shadowy past leaves room for skepticism and possible betrayal. The pair must put aside their differences and work together to stop his parents from their reign of terror, a journey that will draw them closer than they ever expected and form a connection that will ultimately decide the future of their world.
