Secondary element

The secondary elements are formed by the mixture of two of the four elements of Inner Sea elementalism: air, earth, fire, and water. Such secondary elements include:

• ice: combining air and water
• lightning: combining air and, possibly, fire
• mud: combining earth and water
• magma: combining earth and fire

The mixing of elements is seen, for example, to occur at the borders between the Elemental Planes. At these planar borders, elemental creatures and outsiders might also be created from these secondary elements.

Elements also form at the borders between the Elemental Planes and other adjacent planes:

• aether, or pure force: combining elements with the Ethereal Plane. Aether can predominantly be found in Ustalav's Furrows, Tian Xia's Valashmai Jungle, Nar-Voth's Court of Ether, and the Mana Wastes, and is the magical force behind telekinesis.
• void: combining elements with the Void

The nature of aether and void is contentious, and elemental scholars disagree on whether these secondary elements are elements at all.

After the recent return of the lost Elemental Planes of Metal and Wood, the formerly secondary elements of metal and wood were recognzied as primary elements.
