You target one Region with this ritual. The Envoy of the Nation that owns that Region must be present for the entire performance of the ritual.
The targeted Region gains the Causeway Trait. If the targeted Region has the River Trait, it also gains the Bridge Trait.
The effects of this ritual last until the end of the fourth event after the current one or another Regional Sorcery is placed on the target (whichever comes first).
You can overcharge this ritual; for every +10 additional Ritual Power you use when you perform the ritual, the ritual affects +1 additional Region. All Regions targeted by a single performance of this ritual must be contiguous with each other (i.e. you can draw a line through all of them without passing through any non-targeted Regions).
If this ritual is performed outside of Veilguard, its required Ritual Power is tripled.
