Umbra, penumbra and antumbra

Shadows

The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. For a point source only the umbra is cast.

These names are most often used for the shadows cast by celestial bodies, though they are sometimes used to describe levels of darkness, such as in sunspots.

Umbra

The umbra (Latin for "shadow") is the innermost and darkest part of a shadow, where the light source is completely blocked by the occluding body. Such an opaque object does not let light through it. An observer in the umbra experiences a total eclipse. The umbra of a round body occluding a round light source forms a right circular cone; to a viewer at the cone's apex, the two bodies are equal in apparent size. The distance from the Moon to the apex of its umbra is roughly equal to that between the Moon and Earth. Because the Earth is 3.7 times wider than the Moon, its umbra extends correspondingly farther, roughly 1.4 million kilometers.

Umbra (World of Darkness)

The Umbra is the spirit world, a shadow or reflection of the real world, in the World of Darkness role-playing game setting. It is inhabited by spirits, gods, ghosts, and various other supernatural beings. The Umbra can broadly be thought of as all realms that exist beyond the mundane terrestrial existence of Earth. Rather than existing as a single universe, the Umbra embraces many versions of reality, forming a multiverse of realms that operate by their own laws. Mages and werewolves refer to this multiverse as the Tellurian, and are the two populations most likely to travel to the Umbra. Other beings, such as wraiths, are permanent inhabitants and have considerable difficulty interacting with the day-to-day reality of Earth (hereafter simply referred to as 'reality' for brevity's sake).

Cosmology

There are three Umbra or Spirit Realms in the World of darkness. The Dark Umbra or land of the Dead, the Dream Umbra or Dreaming and the Spirit Umbra or true Umbra. When people say Umbra they usually mean the Spirit Umbra. This Umbra (in fact all three Umbra) is structured according to nearness or closeness to mundane Earth. However, this is more a matter of resemblance to Consensus reality than physical distance. The exception is Technological Videre where there is direct link between changing laws of surrounding conditions and distance from Earth surface.

Fictional character biography

Her real name is Tasmia Mallor and her homeworld is Talok VIII. She has the power to project darkness. Like all Talokians native to Talok VIII, she has dark blue skin and pointed ears. The Talokians of Talok III such as Mikaal Tomas have light blue skin. She and her cousin Grev (Shadow Kid) received their powers from their ancestors, whose spirits reside in a cave on Talok VIII (Talokians practice ancestor worship). As her ancestors before her from the past thousand years, Tasmia is the hereditary shadow champion of Talok VIII. Her 20th century ancestors, Lydea Mallor and Lyrissa Mallor, were also shadow champions and members of the interstellar police force L.E.G.I.O.N.

Fobia

Fobia is a Mexican Rock en Español band from Mexico City. The current line-up includes vocalist Leonardo de Lozanne and guitarist and lead songwriter Francisco "Paco" Huidobro. The rhythm section is made up of ex La Ley drummer Mauricio Claveria, former Caifanes, Jaguares, and La Barranca bassist Federico Fong, and keyboardist Dario González Valderrama.

History

The band was formed in 1987 by Lozanne and Huidobro, brother of Micky Huidobro of Molotov. The original lineup consisted of Lozanne, Huidobro, bassist Javier Chá Ramirez, keyboardist Iñaki Vazquez, and Gabriel Kuri on drums. Kuri was later replaced by Jorge ‘la Chiquis’ Amaro who was followed by multi-instrumentalist Jay de la Cueva, (lead singer of the Mexican hair band Moderatto).

Fobia was one of the original Rock en Español bands to emerge from the Mexican Rock en Español / Rock en tu idioma (Rock in your language) boom of the late 1980s, alongside Caifanes, Maná, Neón, Maldita Vecindad y los Hijos del Quinto Patio and Los Amantes de Lola; all of which followed in the footsteps of Soda Stereo – who by the late 1980s had amassed a huge following in the Americas. In December 1987, RCA Ariola de México held a "Rock en tu idioma" battle of the bands contest in Mexico City. Fobia was eliminated early on and Los Amantes de Lola went on to win the contest. In spite of their early elimination, executives from Ariola decided to schedule an appointment with Fobia. According to legend, the band missed their meeting with Ariola because they weren't able to enter the building due to problems with security. Following the incident, the band's luck improved. Saúl Hernández of Caifanes produced their first demos and Ariola eventually signed them.

Fobia (album)

Fobia is an album released by Mexican rock band Fobia. Their self-titled debut album was released in 1990. The songs are primarily themed around common phobias and anxieties, filled with dark humor and melodic music inspired by British bands like The Cure. Songs like Los muñecos and Las moscas deal with the fear of dolls and flies respectively. Other songs like Dios bendiga a los gusanos and El crucifijo deal with the anxieties of love. El microbito delivers humor and a quick change of pace towards the album's finale. It is worth noting that the songs listed above are all hits.

The band received critical and commercial success, added to the fact that Rock en español was going through a revival at the time and new bands seemed to come out of the woodwork.

The original lineup was:
