“Zireth always speaks in hushed tones and glances nervously toward the shadowed alleys outside. He refuses to sell to obvious law enforcement types, and often tests customers by requesting obscure knowledge of the item’s source or spell components before agreeing to a sale. The shop only opens after sundown and is located behind a false wall in a rundown tavern basement. Regulars whisper that Zireth once imprisoned an angry demonic entity inside a scroll — and that it still tries to speak through the ink.”
