When the mage casts the Retainer spell, a receptacle for magical energy appears, he then casts several spells (up to 2 spell levels per level of caster, Max 20th or 40 spell levels) into it.  At a latter date, (within one day per level) the caster may trigger the retainer with a full round action. Once triggered, a burst of magical energy is released and twice the level of spell levels retained must be expended from the memory of the caster. This eruption of magical energy powers the retained spells and they act as if just cast.  If the mage does not currently have a total number of spell levels equivalent to the total retained, then all spells fails. If the retainer is dispelled before it is triggered, all spells retained are lost.
