Walks Unseen is Nessa's Codex, a book from her world that witches use to contain their magical research and communications.

This toplevel will contain relevant notes on the rules and history of magic from Nessa's worlds, spells Nessa has learned (and which ones she's regained) and messages she's shared with other witches.

Nessa regained Walks Unseen on August 23rd, after Physical Education 102.
