+
+// Anima:
+// - Very broad categories of magical energy.
+// - Influences things within the area of effect (high levels of water anima/low levels of fire anima -> harder to light things on fire).
+// - Modifies the chances of spellcasting in the area of effect (high levels of sky anima makes air spells easier).
+// - Higher or lower intensities associated with entities/areas.
+// - Has an associated subset of potentia that can be refined from local anima (sky sign -> air and water anima, etc)
+
+// Local events that create temporary powerful anima sources:
+//  - sacrificing an animal spikes waning and blood anima in the immediate vicinity to boost/enable particular workings
+//  - burning incense, taking drugs, scribing a circle
+
+// Process notes:
+// 1. mob wants to cast a spell
+// 2. retrieve local anima (turf + area)
+// 3. retrieve personal anima (aura extension)
+//   a. effective anima - local anima +/- (personal anima * strength of will)
+//   b. very high will + personal anima can override local anima
+// 4. retrieve spellcasting condition of the mob
+//   a. stressors mean poor spellcasting focus
+//   b. nutrition/stamina are needed for fuelling the spell
+// 4. if anima state or conditions do not allow spell, fizzles
+// 5. spellcaster's personal aura and will are applied agains the target's personal aura/will (for mobs) or just ambient anima for inanimate objects
+// 6. effect of spell is scaled based on how much stronger (or more effectively aligned) the spellcaster is
