"Is there a range limitation to runes? Someone with the permission to be there and knowledge of the defences could take an unorthodox entrance like the roof and bypass the defences that way," Ryuuko wondered, doing her best to memorise the magical information whilst translating it into more mundane terminology. Barriers presented an analogy to walls and doors themselves, simply improved, and area wards had a similarity to biometric identification or even simply cameras. Runes of a limited range could represent even more focused cameras... or traps triggered around them, perhaps the patrols of guards.

The heiress pulled away from the red light, considering where a flaw could be. The important thing was to work out if magic innately protected against unexpected methods of entry. The floor and ceiling when you had up to date plans of the building would be easily exploited if not covered for. Even a few good protections around the target with a mage able to break them were meaningless if the alarms were silenced and the outer defences skipped.
