This guide is aimed at intermediate spellcasters, especially those capable of channeling at least 5 units of arcane energy.

It should be treated as pre-requisite material prior to attempting to cast any spell regarding instantaneous transporation to an unseen point not expressed relative to the caster.

Spatial Dimension

A spatial dimension is a dimension which can be traversed solely through physical motion, such as walking, riding a boat, etc.

It is a common concept that all spatial dimensions can be represented through 3 linearly independant vectors, or basis vectors.

Extra-Planar Dimension

An extra-planar dimension is a dimension which can not be traversed solely through physical motion.

It is generally believed that the number of extra-planar basis vectors is at least two.

Basis Anchor

A basis anchor is a specific point and orientation within spatial and extra-planar space, usually matching the location and rotation of a particular mass.

Generally basis anchors must be formed within extremely large objects to be affected by the object’s rotation in any meaningful way.

Finding Basis Anchors

A spellcaster may be capable of using a basis anchor if they know the specific properties of the anchor. The most common ways of knowing the basis anchor are as follows:

• A creature will intrinsically be linked with the primary basis anchor of the the plane they are born on (this link is often exploited by casters of ‘Banish’).
• Usually the sigil sequence of a teleportation circle will encode the basis anchor properties, as well as an offset from that anchor.
• Basis anchors can be detected and decoded if the object they are associated with is visible, this usually takes many weeks or months.

Plane

A plane is defined as a distinct location along an extra-planar dimension.

Inner Plane

An inner plane is a plane which has at least one extra-planar dimension equal to that dimension for all other inner planes (including Neoter). There are currently 9 known inner planes.

Outer Plane

An outer plane is a plane which does not have any extra-planar dimension equal to an inner plane.

Convergence

A convergence is an event in which the total distance between two planes (combined spatial and extra-planar) is within a certain value.

Standard vs Compatible convergences

A standard convergence is defined as the local minima of the total distance of the planes, whereas compatible convergence is defined as the planes being within the distance required for a particular spell.

It is generally agreed that all inner-planes are in a permanent state of standard convergence, compatible with most spells.

Convergence Requirements of common spells

Note: The compatible convergence of Teleportation Circle and Teleport decreases as energy increases, causing inter-planar travel to be possible.
