The "Mirror with the Leer" as Erasmus and/or Fenrus calls it, is a magic mirror with a dragon-shaped handle. It has the ability to reflect spells back to its caster, much like the Reversal spell.
Erasmus apparently lent it to Henry the Hermit, and forgot about it (he thought that he misplaced it somewhere). Henry in turn gave it to Yorick, the "Brigand Warlock". Yorick intended to use the mirror to disenchant Elsa, until he found out that it can't be used to reverse already cast spells, and the mirror remained unusable on Elsa's desk.
The Hero later used the Mirror against Baba Yaga's Transformation spell, turning her into a frog.
It is unknown if the Hero returned it to Erasmus.
