Cave

A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos.

Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking.

Types and formation

The formation and development of caves is known as speleogenesis. Caves are formed by various geologic processes and can be variable sizes. These may involve a combination of chemical processes, erosion from water, tectonic forces, microorganisms, pressure, and atmospheric influences.

It is estimated that the maximum depth of a cave cannot be more than 3,000 metres (9,800 ft) due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonate rocks.

The Cave (video game)

The Cave is a puzzle-platform/adventure video game developed by Double Fine Productions and published by Sega in January 2013 on the PlayStation Network, Nintendo eShop and Xbox Live Arcade storefronts via the PlayStation 3, Wii U and Xbox 360 consoles and on Steam for Microsoft Windows, OS X and Linux. It was later released on October 3, 2013 on iOS devices, and on December 2, 2013 on the Ouya.

The game was created by Ron Gilbert, building on an idea that he has had for nearly twenty years about a cave that lures people into it to explore their darker personality traits. The game is rated "teen" for blood and violence. The game borrows concepts from his earlier 1987 game, Maniac Mansion, in which the player initially selects three different characters from a cast of seven to explore the Cave. Many of the game's puzzles require the three characters to work in coordination to complete, while some puzzles are specific to the unique abilities of a character; in this manner the Cave can only be fully explored through multiple play-throughs.

History

During a stockholder meeting in August 2011, the company changed the English company name to 'CAVE Interactive CO.,LTD'. However, the foreign www.caveinteractive.com domain name had already been established in May 15, 2011.

Key staff members include Tsuneki Ikeda (director and COO) and Makoto Asada (game development department head) who left the company in 2013. On January 24, 2014, community manager "Masa-King" announced that the Cave-World Twitter and blog were shutting down on February 28, 2014, terminating all existing English social media presence in the west.

Realm

A realm /ˈrɛlm/ is a community or territory over which a sovereign rules; it is commonly used to describe a kingdom or other monarchical or dynastic state.

The Old French word reaume, modern French royaume, was the word first adopted in English; the fixed modern spelling does not appear until the beginning of the 17th century. The word supposedly derives from medieval Latin regalimen, from regalis, of or belonging to a rex, (king). The word rex itself is derived from the Latin verb regere, which means "to rule". Thus the literally meaning of the word realm is the territory of a ruler, traditionally a monarch (emperor, king, grand duke, prince, etc.).

"Realm" is particularly used for those states whose name includes the word kingdom (for example, the United Kingdom), as elegant variation, to avoid clumsy repetition of the word in a sentence (for example, "The Queen's realm, the United Kingdom..."). It is also useful to describe those countries whose monarchs are called something other than "king" or "queen"; for example, the Grand Duchy of Luxembourg is a realm but not a kingdom since its monarch holds the title Grand Duke rather than King.

Desire realm

The desire realm (Sanskrit: kāmadhātu) is one of the trailokya or three realms (Sanskrit: dhātu, Tibetan: khams) in Buddhist cosmology into which a being wandering in saṃsāra may be reborn. The other two are the form realm, (Sanskrit rūpadhātu) and the formless realm (S. ārūpadhātu).

Within the desire realm are either five or six domains (Sanskrit: gati, also sometimes translated as "realm"). In Tibetan Buddhism, there are six domains (Wylie: rigs drug gi skye gnas ) and in Theravada Buddhism there are only five, because the domain of the asuras is not regarded as separate from that of the devas. Taoism also features the five realms.

The Śūraṅgama Sūtra in Mahayana Buddhism regarded the 10 kinds of xian as a separate Immortal realm between the deva and human realms.

The thirty-one realms are also known as the "thirty-one paths of rebirth", the "six paths of suffering", the "six planes", and the "six lower realms". They stand in contrast to the higher attainments of the Ten spiritual realms.

Realm (British magazine)

Realm is a picture magazine available in the United Kingdom. It focuses on sites and topics of interest to tourists from North America, and carries frequent coverage of the British Royal Family and British government.

It is not to be confused with the short-lived Canadian magazine, also called Realm.
