  • DiaryFirst attempt: requested a wolf. Got an otter. She stole my glove, ate the fish, and came back the next time. I have stopped asking why.
  • DiagramSummoning circle: verify the creature's landing space before opening the gate. Daisy prefers a dry patch and objects to smoke.
  • FormulaPotion note: moonlit water, a drop of blue pigment, and a spoken description of the face you hope to deceive. This is an experimental flavoring recipe, not a substitute for a legal alchemical formula.
  • WarningDo not mistake a convincing illusion for a creature that can answer a call. The distinction matters most when the door is already open.

The book itself

Daisy, a perfectly ordinary otter, has answered Strago's Summon Animal spell ever since his first botched attempt. She is not an illusion, and the book's notes insist she always returns home unharmed.
The book includes Strago's personal notes on potion brewing and magical item crafting. These are workshop annotations, not additional spell effects or substitutes for Pathfinder crafting rules.
An illusion can deceive the senses, but it cannot make a summoned creature imaginary.

The caster

  • Arcane wizardStrago Mistfall
Studies: Illusion, with a practical interest in conjuration and planar boundariesManner: Patient and courteous, with the careful manner of someone who assumes every stranger may be a real person concealed by an illusion.Focus: A small brass-framed mirror, used to trace spell diagrams and direct the book's shifting illusions.Quirk: Introduces every summoned creature by name, even when he has never met it before, and keeps a fish-shaped bookmark for Daisy.Wants: Discover why certain summoned beings seem to recognize his invitations, and find a safe way to contact a vanished planar correspondent named in the book.Strago Mistfall is a boundary-school wizard who studied how perception and planar thresholds overlap. His early experiments with calling creatures produced more surprises than answers, most notably Daisy, a common otter who keeps appearing whenever he casts Summon Animal.

The book

A midnight-blue, brass-cornered codex bound in soft gray leather. Its pages shimmer like thin panes of glass, and tiny painted creatures appear to move between the inked diagrams when the book is tilted.

2A frightened fey envoy claims the brass clasp on the book is a seal, and that one of the names written inside belongs to a being trapped behind it.
3A rival illusionist has stolen the codex and is using its summon notes to impersonate Strago. Daisy recognizes the impostor, but nobody else believes an otter.
4Strago's old potion and item-crafting notes include a sketch of a missing workshop hidden somewhere beyond the Material Plane.
