This can be found in Commedia, in the high desert just a few hours dragon flight from the Sanctuary. Inhabitants of the Sanctuary worked with Jayden and Mitena, from the Initiative, to decode the mystery of how to create a portal using an ancient artifact of painted animal hide and the power of storytelling.
This portal opens into Kaleidoscope and the oldest dragon in Sanctuary, Flies True on Strong Wind, will be the first to explore that side. This is a stable, two-way portal that connects two places in Verses with highly mutable realities leading to shifting maps. The portal appears to shift with this movement and maintains the connection.
Introduced in story #28 Too Much History.
