In Dungeons & Dragons, fantasy role-playing game, Arborea or more fully, the Olympian Glades of Arborea, is a chaotic good-aligned plane of existence. It is one of a number of alignment-based Outer Planes that form part of the standard Dungeons & Dragons (D&D) cosmology, used in the Planescape, Greyhawk and some editions of the Forgotten Realms campaign settings.
Arborea is also referred to as "Olympus" or "Arvandor", though technically those names describe separate realms within the plane. Arborea is stylised as a peaceful plane of natural beauty with a multitude of thriving environments. Much of the plane is dominated by vast tall forests, but also includes glades of wildflowers and fields of grain. As a plane that also embodies chaos, it has a wild and often sudden nature. The weather can change drastically at short notice, changing from warm sunshine to raging winds and back again in just a few minutes.
The plane known as Olympus was mentioned for the first time by name in the article "Planes: The Concepts of Spatial, Temporal and Physical Relationships in D&D", in The Dragon #8, released July 1977. The plane was mentioned again in an appendix of the known planes of existence in the original (1st edition) AD&D Players Handbook, published in June 1978, where it was described as "The planes of Olympus of absolute good chaotics".
Arborea is a town and comune in the province of Oristano, Sardinia, Italy, whose economy is largely based on agriculture, with production of vegetables, rice and fruit.
Arborea was built by the fascist government of Italy in the 1920s, after the draining of the marshes which covered the area. The village was populated by families, mostly composed of peasants, who came from the regions of Veneto and Friuli in north-eastern Italy.
Arborea is named for and lies within the medieval Giudicato of Arborea, which had its capital, at various periods, in nearby Tharros and Oristano. The town was originally named Villaggio Mussolini (with which it was inaugurated on October 29, 1928), by the fascist government. Less than two years later, the name was revised to Mussolinia di Sardegna ("Mussolinia of Sardinia", to distinguish the town from Mussolinia di Sicilia, now Santo Pietro in the commune of Caltagirone, Province of Catania). The current name was adopted after World War II.

Charniodiscus is an Ediacaran fossil that in life was probably a stationary filter feeder that lived anchored to a sandy sea bed. The organism had a holdfast, stalk and frond. The holdfast was bulbous shaped, and the stalk was flexible. The frond was segmented and had a pointed tip. There were two growth forms: one with a short stem and fat frond, and another with a long stalk, elevating a smaller frond about 50 centimetres (20 in) above the holdfast. While the organism superficially resembles the sea pens (cnidaria), it is probably not a crown-group animal.
Charniodiscus was first found in Charnwood Forest in England, and named by Trevor D. Ford in 1958. The name is derived from the fact that Ford only described a holdfast consisting of a double concentic circle, his species being named Charniodiscus concentricus. Later it was discovered that a frond (Charnia masoni) was part of a closely related organism. Charnia differs in the branching structure in the frond.
Charniodiscus specimens are known from across the globe dating to around 565 to 555 million years ago.
