Just to clarify, what is there to search? Based on your description, we have a manor house. (New? Abandoned? In poor repair?) Are there any existing outbuildings? I'm assuming the rest is pretty much open ground, with perhaps some scrub. Is that accurate?
Based on my understanding, the following spell should be possible:
Sense the Presence of People
InCo 20
R: Touch, D: Mom, T: Structure
This spell allows the caster to instantly detect whether there are any people present in a structure, and if so, where.
(Base 4, +1 Touch, +3 Structure)
This is based on the guideline "sense very general information about a body" (i.e., its presence and its location). Clearly, if any hiding people had magic resistance, it would have to penetrate.
Galan intends to cast this spell on the manor house. (And possible elsewhere if there are other buildings.) Please let me know if it's not a valid spell.
Assuming it is a valid spell, here's my roll:
CT = [stress die + 8 (In) + 22 (Co) + 1 (Sta) + 3 (talisman) + 5 (Aura)]/2 = [stress die + 39]/2
CT = (Spontaneous spell: 1D10+39 = [6]+39 = 45)/2
CT = 23
Also, Galan will check out the area (including the building) with his Mark I eyeballs. That's presumably an Awareness(search) check:
Roll = stress die + 2 (Awareness) + 1 (Perception) = Awareness check: 1D10+3 = [2]+3 = 5
I'm assuming a stress die in case there's something hiding. I'm also guessing that with that roll he didn't find anything.
I'll do an IC post when I get the results of my rolls.
