So, my maga is about to embark upon a journey to a demon-infested forest to fulfill her destiny and free her long lost sister, who is of dubious realm alligment herself. Chances are she won't survive, so she's decided to leave certain assets to her godson, a foundling boy who resides at our covenant. We're talking a number of infernal devices, and some information I promised the quaesitores I'd never share. And my memoires of course.
The boy is too young to get the inheritance straight away, and my sodales will most likely attempt to interfere when they find out what I'm doing. They mean well, but alas, they are also misguided, and unlikely to understand the importance of sharing such things with a toddler.
So I decide to hide the goodies, and use a creo mentem effect with a watching ward to tell him where they are when the time is right. Which is where the 'simple condition' comes in. Is that something like jumping up and down three times, or could I use something like a planetar constellation as the trigger? He mustn't get this stuff before he's an adult, so I need something that will trigger in 15-20 years. If absolutely necessary, I can rely on one of the magi in the covenant to trigger the ward without asking too many questions, but he's a sweet, innocent lad and I'd rather not involve him in anything infernal. Any ideas?
The watching ward will be level 30 or 35, the CrMe effect will be level 10 at most, so I'll have some room for a minor intellego effect. My intellego isn't great, so I can't spont much more than 10, unless it's InVi or InMe.
