Solas didn't yet know that he possessed magical abilities; after all, the books in the library contradicted each other so often that it was easier to assume magic didn't exist at all. Still, the secrets of the arcane called to him, even in the modern books' lies there could be found the slightest truths if one dug deep enough. The new principal was in a less visible corner of the school library, aged and ragged books in two piles on either side of him. He'd been here since noon, and now that it was pitch dark outside, the young wolf had set up a lantern on the floor by which to continue reading. It was all fascinating stuff; images of dragons and wraiths and fairies practicing the wildest magic imaginable flew through Solas's mind as he turned the pages, referring less and less often to the dictionary he left open beside him for those big words he tended to encounter.
But what was theory without some hands-on experience? Though he doubted they would actually work, Solas had set a large whiteboard on the floor and tried several of the rituals described by his books. Out of the five he'd tried today, only one of them had worked, and that was just a spell for causing a candle to go out. Which could just as easily have been a draft from the nearby window.
Squinting at the words in the low light, he decided to try some of the more powerful stuff. Class-D spirit summoning, this book promised, would give him insight into the world from the eyes of a spirit without them being able to harm him. The only thing was that the spell called for energy to fuel it, but didn't specify what kind of energy. Out of boredom, he decided to go all out; instead of marker, this time, the principal aimed a claw to make a careful incision on the tip of his paw, crimson slowly soaking through the pure white fur until it came to a slow drip. Using this blood, he created the summoning circle as the book described; he messed up a few times, but the blood didn't really come off that easily, so he did what he could to wipe the mistaken markings away, leaving barely visible smudges behind.
As for the lighting and offering, he arranged the six candles as the page described, and brought up a fallen fox for the blood sacrifice. The fox had been caught attacking the group's kittens, a stray Exiler by the look of its scars and tattoos, it was only fair that its corpse be used to contribute to the learning they had disrupted. Surprisingly, Solas didn't really mind the smell of decay. It was strange, perhaps, but nothing he couldn't handle.
Finally, Solas held the book in front of his face, reading aloud what runes he could understand from the page's dim light.
