Here is a big one, which was finished shortly before play in our Saga started and creation of our Covenant was part of displaying it.
Aegis of the Regio (OR Major Breakthrough 45 [Note: The original AotH was a Major Breakthrough])
Sources of Insight: -
Relevant Spells: Versions of AotH with Size, InVi spells capable of sensing the interwoven layers of a Regio and alignment of the Aura.
Stipulations: At least 15 points each of this breakthrough must come from variations of AotH and InVi spells for studying the interwoven nature of a Magic Regio in an Aura.
Effect: The ability to cast an AotH that is interwoven into a Magic Regio, allowing it to affect multiple tiers at the same time.
All levels of the Regio are interwoven and can be affected by an Aegis cast over a whole lower level. To achieve this, the diameter of the Aegis must be greater than the diameter of the 1st tier, plus a fraction of the higher tiers. This fraction is half for the 2nd tier, a quarter for the 3rd tier, an eighth for the 4th tier, and so forth. At least Size +1 must be taken and the entire Regio must be covered (entire 1st tier plus fraction of higher tiers). The interweaving can only be performed in a Magic Regio, with the ability to perform it in a different Realm Regio being a possible Breakthrough.
The Aegis of the Hearth does not extend outside of the Regio. Beings of Might and spells within the mundane level are unaffected by the Aegis, though they must overcome it to gain entry into the Regio.
