Re: OOC
In the exact description of the ritual, no... The problem is, that the ritual is at the back in the book, but the explanatory text is in the front chapters, amongst the magical theory (where is a reference to the ritual). It would take many time for Klaus to browse through the magic theory, even if not understanding it, but trying to determine it's approach, determine it's conceptualization if it's heretical or not... if he's expenditious, he can do it until late night (maybe before midnight), but if not, then the other version remains, that would require the whole night.
