Elemental World. King Sapphire

What can be more heartbreaking than a heart bleeding for a person who needs you only as a thing? Only one thing is worse: to voluntarily deprive yourself of freedom in order to save his life. And also — to end up in the darkest abyss of underground caves among stalactites, fungi, and precious stones. Just as cold and dangerous as the soul of its owner — the accursed king nicknamed Sapphire.
