Lord Raddalin leads different tribes in an uneasy alliance. A discovery in the north could give him even more power, and he's determined to have it. A scribe and jarl's son now hold the future of the kingdom in their hands.
Starting with Ilme the scribe who is also an unwilling spy for her aunt, we see the power of rune magic. Using the elements in different combinations, anyone who understands runes can use them. It can enhance building things, battles, or assist the people around them. Up in the north, Gunnar found the runic essence mine and its guardian; having a mine means its essence doesn't have to be scrounged for, but taken at predictable intervals to create new runes for use. It's a find that ultimately helps Lord Raddalin create the kingdom he hoped for, while in the north, there are still tribes that exist and rule through force. Gunnar's father Valjin despises magic and only believes in his own might, which over time puts him into a difficult position as he weakens and refuses to see it. War had broken out in the past, and there's the looming threat of future wars.
The book goes through lore from the Runescape game, which I hadn't played. Without the game knowledge, I still enjoyed the world-building. It's a fantasy tale that spans decades and borrows a lot from our history: what happens when technology begins to outstrip those who control it, and how will that affect those people without it? Here, the technology is magic done through runes, making it more egalitarian than the style relying on innate ability or ritual. We know how each of the main characters feels about war, the lies told to gain access to the mine, and the losses that hurt them and make it harder to discuss anything calmly.
This book is less obvious court politics and intrigue than the source of magic, religious belief, and interpersonal tensions. We see Ilme and the other wizards, and the edges of court that she's aware of as a scribe and then as a wizard. Gunnar's people are considered barbarians, but the hurt he holds is easily understood. The friendship they had lasted for years until it didn't, and the fallout of the original lie had far-reaching consequences. Each section of the book covers a different period of time, and it all comes down to the same question posed in the beginning: Will Ilme be used by others around her, or will she be strong enough to choose a direction for herself? It's especially true in the final section when she's aware of the very real risks to the wizards and the country. Overall, it's a story that kept me hooked to see how it ended.
