Realm Gate Bangle
A bangle owned by Holly and traded to her by Tarquin Primrose-Morton in exchange for a copy of The Styles Map.
It opens portals with the keyword "Ori Primus" followed by stating the target realm and fixing it in your mind, a good description will work if you've not seen it. The portals last around 2-3 minutes. Can be used to follow the hops on the map there is no way to directly jump deep.
