How do Narora interact with Portal spires on their fortress Source wells?

Fortress Source wells are Adjacent to the Fortress Gate Hex. Units may freely deploy directly into this Spire. Naroran heroes may Teleport from another Naroran Rift in the play area to this Spire. This is not considered Returning to the Fortress gate; the Naroran heroes still need to spend Movement to move onto the Fortress Gate Hex. Naroran minions cannot normally Teleport to a Spire on a Fortress Source Well because they are required to make Progress while moving if they are able to.
