A mage with a sanctum may create a synthetic Verge known as a Demesne by extending the Supernal connection within a soulstone[1].
A Desmesne offers a +2 die Yantra bonus to spells that utilize its Ruling Arcana. Furthermore, as long as a spell that qualifies for the bonus doesn’t leave the Demesne, it doesn’t risk Paradox unless a Sleeper is present at some point during the spell’s duration. Spells cast in natural Verges are not subject to Dissonance, but those cast in Demesnes are. Sleepers suffer Quiescence as usual. This makes challenging a mage within their Demesne incredibly dangerous, as they can Reach as much as they want without fear of Paradox.
Neither the stone nor the spell need come from the sorcerer who uses it. By combining multiple soulstones, a mage can create a larger Demesne, although no more than 5 soulstones can be used in any one Demesne[2]. Mages may travel to the Astral Realms from a Demesne powered by her own soul stone, a stone with a soul on the same Path, or through any Path’s stone (with the permission of the sorcerer whose soul resides within it). Once given, permission cannot be rescinded until the beneficiary returns.
A Verge or Demesne’s Yantra bonus is limited by its semiotic associations, as is usual for Yantras. A Stygian Verge that’s filled with metal but no aspects of Death won’t help a mage bind ghosts, but will help him create strange alloys. Mages typically equip Demesnes with equipment and symbols that support the spells they plan to cast.
Verges and Demesnes both provide a +2 die bonus to rolls to summon Supernal entities from the realms they’re connected to.
