Spellbook of al-Wasat

The spellbook of al-Wasat was created by Kuiril al-Wasat, the elf who disjuncted the Horseman of Death and took his place. It is missing several pages, including, it can be presumed, the page that contains the formula to perform al-Wasat's targeted disjunction.

It was protected by an passcoded arcane lock (which could not be supressed by knock) and a binding of behir leather which imparted a galvanizing spell targeted at any who touched it.
