Perpendicularity

From The Coppermind
Revision as of 23:53, 11 September 2020 by LadyLameness (talk | contribs) (Undo revision 132284 by Niser Resin (talk) Oathbringer throws in what happens after people go through Devotion's Perpendicularity (even then, it is likely the plasma storm that would kill people and not the perpendicularity itself). We also do not know that only Preservation is able to make their perpendicularity bestow power - this might be possible by any Shard.)

At these points, Physical matter, Cognitive thought, and Spiritual essence become one--and a being can slide between Realms.

—From Khriss's essay on the Drominad system[1]

A perpendicularity is a stable junction between the Physical, Cognitive, and Spiritual Realms. They are used by worldhoppers such as Hoid to go from planet to planet. They are formed through the concentration of Investiture. Because of this, they are most commonly found at places where a Shard's power is focused, often in the form of a pool of liquid. A Shard can control where their perpendicularity manifests.[2]

Mechanics[edit]

Perpendicularities are formed at locations with a large concentration of Investiture. The concentration of Investiture brings the three realms closer together and allows travel between them.[1] The proximity of the realms also makes Soulcasting easier.[3] They occur naturally when a Shard spends lots of time on a world.[4] Generally, leaving a planet would cause the Shard's perpendicularity to disappear. As a result, their presence is often used to indicate the presence of a Shard. Special circumstances, however, can prevent the perpendicularity from disappearing, and there is at least one Shard that fits these circumstances.[5][6] Aluminum can be used to take liquid from a perpendicularity, and it will stay Invested.[7] They can be used to see into the Spiritual Realm.[8] Nightblood is able to collapse a perpendicularity.[9]

Known Perpendicularities[edit]

Scadrial
  • Ruin: the pool below the Pits of Hathsin was Ruin's perpendicularity; it was the main path used by inter-world traders before it was destroyed by Kelsier.[10]
  • Preservation: Preservation's perpendicularity was the Well of Ascension. It served as Ruin's prison, making it extremely dangerous.[10]
  • Harmony: Whether Harmony has a perpendicularity, and whether it's one or two perpendicularities, has not been revealed.[11][12] An article in The House Record mentions a woman coming across a perfectly blue pool somewhere in the mountains in the Southern Roughs, and a sudden appearance of a strange figure by the pool. It's possible, though not confirmed, that this could be Harmony's perpendicularity.
Sel
Threnody
  • Threnody does not have a stable perpendicularity, but rather a number of unstable, unpredictable ones of a morbid origin.[14] They may possibly have something to do with the creation of Shades, although the fact that the Shard of Ambition has died near the system has far greater influence on their creation.[15]
First of the Sun
  • First of the Sun is notable for having a perpendicularity, presumably Patji's Eye, without a Shard in residence.[1] However, Patji is an avatar of Autonomy,[16] which is likely the cause of the perpendicularity.
Roshar
Nalthis
  • Endowment: The location of Endowment's perpendicularity is unspecified. It is, however, located somewhere in the jungles of Hallandren. The Tears of Edgli owe their existence and their unusual properties as dye material to soaking up the Investiture flowing up from the perpendicularity.[22]
