Darkvision is the ability to see normally in total darkness. Darkvision is similar to normal vision, and does not allow the person who possesses it to see invisible, or otherwise hidden or obscured things (other than those things obscured by darkness). Those using darkvision see things only in black-and-white, and it is not spoiled by the presence of light. Darkvision is possessed most commonly by creatures who are (or once were) native to the Darklands. It is also common among many other races and creatures.
