Tempus (pronounced: /ˈtɛmpʌs/ TEM-pus), was the greater god of war in the Faerûnian pantheon. The dogma of the Lord of Battles was primarily concerned with honorable combat, forbidding cowardice and encouraging the use of force of arms to settle disputes.

To the Foehammer, war was a force of nature to be respected, for it had the power to remake civilizations.
