Kathtairr is a landmass in the southern ocean on Athera, across the world from the continent of Paravia. The land is described as empty and lifeless, scorched by drakefire long before Ath Creator sent the Paravians to Athera.
According to the author, what happened on Kathtairr was an extreme event and the "reason" underpinning the first dreaming of the drakes that generated the response of the Paravian arrival as Ath's gift. There are sections of the planet still "wounded" and this area is one of them, and there is a reason why it cannot be healed.
