'''Cultivation's Perpendicularity''', referred to as "the pool" or the "water of life" by the [[Unkalaki]],{{book ref|sa3.5|15}}{{book ref|sa2|46}} is the only known stable [[perpendicularity]] on [[Roshar]]. Like all perpendicularities, Cultivation's Perpendicularity allows for travel between [[Roshar]]'s [[Physical Realm]] and [[Shadesmar]]. Although it is possible to enter Roshar through other means, they are known to be highly unstable; as such, this appears to be the main method by which [[worldhopper]]s arrive at the planet.{{book ref|sa3|93}}

Cultivation's Perpendicularity is located in the [[Horneater Peaks]] on Roshar. It is either one or all of the [[Horneater Oceans]], warm bodies of water that allow people to live there despite the high altitude. It's filled with ordinary water at the top; however, beneath this layer, it appears to be made of something else, likely the liquid [[Investiture]] of the [[Shard]] [[Cultivation]].{{book ref|sa2|46}} It's possible that living near Cultivation's Perpendicularity can affect people, as among the [[Unkalaki]]--the Horneaters--there are people known as ''alaii'iku'', or [[Sighted]], who are capable of perceiving [[spren]] that are normally invisible to the human eye.{{book ref|sa1|21}}{{ref|text=However, it's also possible that this is the result of their [[Singer]] ancestry, as Singers have been shown to perceive spren more than humans do.}} The Sighted are also considered the guardians of the perpendicularity.{{book ref|sa3.5|15}}

== History ==

Sometimes while swimming in the Oceans, the Horneaters would visit the "place of the gods", implying that the [[Unkalaki]] would sometimes travel through the perpendicularity, albeit briefly.{{book ref|sa2|46}}

Both [[Wit]] and [[Azure]] used this perpendicularity when arriving on [[Roshar]]. The former passed through while [[Rock]] was still at the Peaks, while the latter likely uses it some time later, chasing a "criminal", presumably [[Zahel]].{{book ref|sa2|46}}{{book ref|sa3|93}}

During the [[True Desolation]], the perpendicularity was assaulted through Shadesmar by the [[Voidbringers]], who took control of, and blockaded, it to control travel, as they believed it would help secure them a foothold in the realm so they could begin to build their own empire.{{book ref|sa3|108}} Though it seemed that the Voidbringer presence in the region was limited to the [[Cognitive Realm]], it still had some sort of impact on the inhabitants of the Peaks.{{book ref|sa3|37}}

Since the [[Fused]] increased their influence in Shadesmar, travelers moving through the perpendicularity have become uncommon.{{book ref|sa3|97}} This occupation gained the area a poor reputation, and travel to the area became increasingly rarer with ships in the area vanishing before they reached their destination.{{book ref|sa3|101}} The Fused began sailing their warships through the region, halting anyone they came upon and demanding tribute of them. Because of this, most spren chose to avoid the region; with the exception of the [[honorspren]] who sent warships to attempt to destroy the Fused's blockades, and [[Azure]] who still believed it to be the safest way to transfer to the Physical Realm.{{book ref|sa3|102}} When she accidentally finds herself stuck in Shadesmar, Azure attempts to convince [[Kaladin]] and the other members of their group that they should try and go to the perpendicularity to transfer back to the Physical Realm.{{book ref|sa3|97}}
