The Cruelty of Magic - Cruel Origins, #1

A warlord seeks the destruction of Runefall, and the end of magic, as a prophecy is met with doubt. Kyra, a young woman capable of wielding rune magic, is called from her hidden city to a temple no one knows about. As Kyra wrestles with a prophecy, and wanting to save her city, a dwarven king leads his people to carve a new home for themselves but instead finds himself approaching divinity. On the other side of the world, a dark sewer hosts a father and son who escaped a tyrannical attack.
They now hide and attempt to summon a golem for protection but learn something about magic that might change the world. Intricate stories and deep lies connect peoples from all across the land. The actions of one may very well condemn the lives of another, even if they never meet. Such is the cruel way of the world and the unforgiving cost of magic.
