Tempus

Tempus's realm of Warrior's Rest was anything but restful. Based in Limbo, the realm was even more violent than that of Avernus, defined by its near endlessly raging battles between demons and devils. Any one that "died" would simply lie on the ground until their wounds healed, at which point they would fight for the one who defeated them. Permanent death was reserved as a punishment for those who showed cowardice on the battlefield, generally in the form of Tempus withholding regeneration immediately before a quick and final death.

Be fearless.
Never turn away from a fight.
Obey the rules of war.

Tempus appeared as a 12 feet (3.7 meters) tall human.

Crisscrossed by wounds oozing with his smoking, wine-red blood, yet he remained unaffected by these injuries.

Appears in battered and bloodied plate mail, his face hidden by a giant war helm, though his gaze remained a palpable force. His arms and legs remained bare (although he did wear gauntlets).

It was Tempus who sponsored the ascension of the Red Knight in her afterlife, he who encouraged her worship, and only he who knew her true name. She looked to him as a father figure and their relationship was akin to that of a fond and protective father with a brilliant daughter that worked hard and successfully in the family business, namely war. The two spent a great amount of time together, mostly looking into the battles of Thalia's past and present, but they also simply hunted or shared stories in his feasting hall.
  Strangely for a god of war, Tempus had very few actual enemies, although he was known to be derisively referred to as "the Butcher" by followers of Eilistraee. Sune considered him a foe for his destruction of beautiful things, but besides her very nature made it hard for others to stay mad at her for long, he considered her flighty and irrelevant, not worth getting into active conflict with or even of mutual dislike.   The one being that deemed Tempus an enemy that he actually acknowledged was Garagos. Once the primary war god of Thalia, the young demigod Tempus managed to defeat him, purportedly winning a century long battle by using his own berserker fury against him, and taking the position of the god of war as the spoils from their duel. The Blood-Reaver's loss to Tempus had only shortened his fuse, and his new incarnation possessed none of his former craftiness or mercy. While Garagos still harbored deep resentment towards Tempus unless his destructive abilities could someday surpass his tactical weakness, he would suffer if they someday met on the battlefield.   The main mystery behind this ancient feud was why Tempus, who lacked any other enemy he cared about, continued to tolerate Garagos's existence. He allowed Garagos to dwell in Warrior's Rest despite him being hostile to everyone else there and some said that he had uplifted the pragmatic and strategic Red Knight so that she could to act as his natural counterbalance. Some sages speculated that Tempus kept him around to act as bait, preferring to let the Bloodreaver lure out potential challengers. Others, meanwhile, suggested that there was one aspect of war that even Tempus found personally distasteful, the rabid rage of a mindless, murderous frenzy, and that he deliberately left it behind with Garagos when he became the god of war.
