Umbra is a simple computer role-playing game, written in Python. The world is randomly-generated for new play every time, but there is an eventual goal and storyline. It was heavily influenced by rogue-like games, Alternate Reality, console RPGs, and the works of H.P. Lovecraft and Clark Ashton Smith.

the darkest central portion of a shadow
(a) The dark inner portion of a shadow, such as the part of the earth's shadow which the moon is in total eclipse during a lunar eclipse; (b) the dark central portion of a sunspot.
dark central zone created by an eclipse.
The complete or perfect shadow of an opaque body, as a planet, where the light from the source of illumination is completely cut off.
The central brightly lit section of a spotlight's cone of light

The central, completely dark part of a shadow.
The dark central area of a sunspot.
1. The inner, dark, cool (3700 K = 6600 °F = 3400 °C) region of a sunspot. The umbra of a sunspot can be up to 12,000 miles (20,000 km) wide. 2. A region of complete shadow resulting from total obstruction of light.
A complete shadow (as of the Moon) within which the source of light (the Sun) is totally hidden from view.
The dark central region of a sunspot.
The dark, inner region of a fully developed sunspot. Has a temperature of about 4,200 degrees and a strong magnetic field.
The dark central zone of the Moon's shadow during a solar eclipse. It is surrounded by the penumbra, the lighter, outer zone of the shadow.
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.
Umbra is an American typeface designed in 1935 by Robert Hunter Middleton. It is an adaptation of the uppercase set of his earlier typeface Tempo Light. The name Umbra refers to its shadow effect, in which the actual letter shape consists of negative space and is defined solely by its black dimensional shadow.
