The Destiny of Kord
Tempus (pronounced TEM-pus), also known as the Lord of Battles, is the god of war. His dogma is primarily concerned with honourable battle, forbidding cowardice and encouraging the use of force of arms to settle disputes.
Tempus was originally one of many potential war gods who emerged from the primordial clashes between Selune and Shar. These gods fought constantly with each other, the victors absorbing the essence and power of the defeated. This continued until Tempus stood as the sole god of war in the Faerûnian pantheon, having defeated and absorbed all of his competitors (with the notable exception of Garagos, whom he defeated but spared). The barbarians of Icewind Dale claim that Tempus original name is "Tempos".
In the Year of Shadows, Tempus' Avatar appeared in a ruined castle in Battledale, just over five miles southwest of Essembra. Immediately following the Godswar, Eldan Ambrose, an Amnian Cleric of Tempus, saw Tempus during a battle in Swords Creek. After the fighting ended, Ambrose followed his god's trail back to Battledale, and found the castle (which originally belonged to Belarus, a long-dead Tempuran). In the ruins of the great hall, Ambrose had a vision confirming the site as sacred to the Foehammer. Ambrose and his allies rebuilt the castle, establishing the Abbey of the Sword.
Tempus is served by the Red Knight, deity of strategy and war planning, Valkur, god of seaboard warfare, and Uthgar, patron of the Uthgardt Barbarians of Icewind Dale. He opposed and is opposed by Garagos, who was formerly known as Targus and worshipped as the god of war in the now-fallen empire of Netheril until Tempus defeated him and claimed his station, reducing the greater god of war to the Demi-God today known as Garagos. Tempus has slain many other deities aspiring to be the god of war, and it is not certain why he tolerates Garagos' continued existence, having already defeated him once. Some scholars in the Realms believe that Tempus' dislike of mindless slaughter and bloodlust prompted him to spare Garagos so that he could represent those more vicious aspects of war. This is supported by the fact that the Tempuran liturgy stressed honourable combat, not wanton destruction.
Faerun is a violent land, and thus by a sheer number of worshipers Tempus is one of the mightiest deities in the Realms. Nearly everyone who has drawn a sword or nocked an arrow has fought alongside a cleric of the Foehammer, and just as many have fought against one. Temples to the Lord of Battle look more like military fortresses than the archetypal temple. They feature barracks, mess halls, armouries, and training grounds.
Due to its tendency to have followers and priests on both sides of any engagement, the Church of Tempus has no central authority that might support one side or the other exclusively. Within a given temple or order, however, there is always a strict hierarchy and chain of command.
