Element

In the real world, classical elements were deemed the most basic form of existence, drawn from observation of the phases of matter, and many objects were considered to be combinations of the four classical elements of Earth, Fire, Wind and Water. In terms of roleplaying, characters have personality, abilities or physical traits relating to a specific element, or the element itself is an affinity to have.

Vanguard
The elements of the fictional world created by ∞, in which characters such as Drake Ignis, Zauss Tajit and Centorion reside. Elements in this world exist as 'umbrella' forms, covering a few interrelated phenomena or types of matter.

Geo
Covers the titles of soil, stone and wood. In more detail, Geo sprites have control over dirt, rocks and plant life. They thrive in environments like forsts and canyons, and are typically the tallest and most solidly-built Vanguard, and usually dark-skinned, black-and-short-haired, and green-eyed.

Hydro
Covers the titles of water, ice and steam. Generally speaking, Hydro sprites control water in all its forms, and many other non-toxic, -acidic and -caustic liquid matter. Hydro sprites are smooth-skinned and move with a flowing grace. Typically have long, black hair that reflects blue instead of white, and have deep blue eyes. Hydro bears total affinities with Geo and Aero, partial with Electro, and is totally opposed with Pyro. It lies neutral with Light and Dark.

Aero
Covers the titles of air, wind and steam. Control over oxygen, and many other non-oxygen-reacting gasses, as well as non-toxic and acidic/caustic ones. Aero sprites are thinly built and lightweight, with grey eyes and grey hair.

Pyro
Bears the brands of Fire, Magma and Smoke. Controls temperature differences to melt or ignite objects. Typically have red/orange eyes and red/orange hair.

Electro
Lightning, Magnetism, Steel and Thunder fall under this category. Powers over electromagnetism, various metals and sound are granted to Electro Sprites, who typically have blonde hair and grey or gold eyes.

Light
Life, Growth, Illumination and Time are subsets of the Light element. The ability to create and regenerate or propogate life, illumination at will, and chronomancy are powers granted to a Light Sprite.

Dark
Death, Decay, Darkness and Space are associated with Dark, though it is important to keep in mind this is not some 'evil' element, and Light isn't a 'good' one. Abilities available to Dark Sprites broadly include: Deconstructing something at any level of it's structure; inducing weakness, rapid aging or erosion into something; the absorbtion and dimming of light; and the warping of the three spatial dimensions as well as gravity.
