The Hylocosm

The hylocosm is a representation of the four basic elemental energies, and the primordial energies, and how they combine on a metaphysical level to make amalgmal energies. These behave as "sub-elements", and are otherwise distinct from the energies that birthed them. Therefore while metal, for instance, is a combination of fire, earth, and extropy, doing a damage combination or otherwise doing stuff with a combination of those damage types or energies is not equal to this.

The Model

                              Extropy
Crystal  Metal    Heat      Light     Lightning  Thunder  Ooze   Acid
Earth    Magma    Fire      Smoke     Air        Mist     Water  Mud
Eskara   Stone    Ash       Darkness  Void       Cold     Ice    Alkali
                              Entropy

Fire, air, water, and earth are base elements, and combine with their neighboring elements to make first order amalgms: Smoke, mist, mud, and magma.

The base elements combine with a primordial energy polarity, either extropy, or entropy to make second order amalgms: Light, darkness, lightning, void, ooze, ice, crystal, and eskara.

Two base elements combine with a primordial energy polarity to make third order amalgms, and otherwise don't incorporate the first, or second order amalgms: Heat, cold, thunder, stone, acid, alkali, metal, and ash.

All four basic elements, plus both primordial energy polarities combine to make the one fourth order amalgm: shadow.

Confusingly enough, the elements aren't always positioned to where antagonistic energies are directly competing. For instance, heat's opposite is cold, not ash. Which makes this map partially pointless! Yay!

The Revised Model

As the above is mostly correct but somewhat outdated (and I'd feel bad just deleting it because it's nicely written and all), here is the more current version of the hylocosm, along with the related telesmic channeling skill name for each element. I will leave the table wizardry to someone more versed in the wiki arcana than I.

Base Elements

Straightforwardly enough, elemental energies are present independently, and occur in all of the following amalgams.

• Earth; Geoturgy
• Fire; Pyraturgy
• Air; Aeroturgy
• Water; Aquaturgy

polar energies

Besides occurring on their own, polar energies are present in second, third, and the fourth amalgam, but not in first order ones.

• Extropy; Viturgy
• Entropy; Thanaturgy

First Order Amalgams

First order amalgams are comprised of two adjacent elemental energies.

• Magma; earth + fire; Magmaturgy
• Smoke; fire + air; Typhaturgy
• Mist air + water; Achlaturgy
• Mud; water + earth; Laspaturgy

Second Order Amalgams

Second order amalgams are comprised of a base element and a polar energy.

• Crystal; earth + extropy; Krystallaturgy
• Eskara; earth + entropy; Eskaraturgy
• Heat; fire + extropy; Thermaturgy
• Ash; fire + entropy; Spodaturgy
• Lightning; air + extropy; Elektraturgy
• Void; air + entropy; Ektilaturgy
• Ooze; water + extropy; Khlediturgy
• Ice; water + entropy; Glaciaturgy

Third Order Amalgams

Third order amalgams are comprised of two adjacent elemental energies and a polar energy. Another way of thinking about it is, third order amalgams are "polarized" first order amalgams,.

• Metal; earth + fire + extropy; Khalkiturgy
• Stone; earth + fire + entropy; Petraturgy
• Light; fire + air + extropy; Lumiturgy
• Darkness; fire + air + entropy; Skotaturgy
• Thunder; air + water + extropy; Keraunaturgy
• Cold; air + water + entropy; Cryoturgy
• Acid; water + earth + extropy; Oxydaturgy
• Alkali; water + earth + entropy; Alkaliturgy

Fourth Order Amalgam

There is only one of these and it is made up of everything else.

• Shadow; extropy + earth + fire + air + water + entropy; Skiaturgy

There are forces and energies that don't fit into the hylocosmic model. For those, see the Paracosmic Model.

For material stuff relating to elements, see Item Infusion. As explained there, energies have magnitude. This is relevant to the hylocosmic model in that, in a three-dimensional representation of the planes, magnitude represents the distance each plane is from the center (and thus its counterparts).
