Soul Stones

Introduction
Soul Stones are the final magical blast that most people will perform before their soul sizzles out and passes onto the next realm. It's created by an effect known as "the hardening" where the soul is hardened into a crystal-like shape and stores its magical potential. The strange properties of these stones said to look like beautiful and valuable gems have yet to be fully documented beyond their inability to be broken or split, and the ability to use other types of magic that it gives to the wielder.

 Miles Baxter:  (alive)

The second last conductor of the traveling orchestra as of the end of king Noct the 16ths reign, he came into possession of a Necromancy stone through strange means. After stumbling upon the scientist's lab in the middle of nowhere and meeting Gerald, a rather rude Nymphilli studying an Enhancement stone. He learned of the consequences and benefits of possessing one. A person holding a Soul Stone near themselves will not only be able to use the effects of the stone, they will passively be affected by the stone. Such is life for Miles Baxter as the second he took the Necromancy stone unaware of what it was he accidentally killed Gerard and became the newest user of the stone. To this day he roams the earth with his orchestra filled with the dead he's raised, being conducted by its own undead conductor named "Miles Baxter".
