The year is 1913 and Adeline Ogilvy makes her way to Vienna, after accepting a career opportunity to transcribe the memoirs of the late Emeryk Quintillus.

Four years attending the Magician's Keep, and Opal believes she's nothing but a disaster and a disappointment. Instead of being able to learn and practice new powers like other students, her one and only ability is placing a thread of magic within the glass figures she creates, which can then be used as a means for cross-country communication. Definitely not combat related, thus she is shocked to learn the Master Magicians have an assignment for her.
Whilst rumours of his master's return circulates throughout the mage community, Alex Verus, Diviner and known "outsider", chooses to ignore the gossip and focus on something else entirely, such as rebuilding damaged friendships.

Taking it upon himself, Alex doesn't hesitate to stage a rescue mission, which just so happens to lead to a shadow realm, belonging to the one and only Dark mage, Sagash.
