Scars of Faerûn
Amaunator is the Netherese solar greater deity of order, the sun, law and time. He is viewed as a harsh but fair deity, revered by many rulers, soldiers and powerful wizards.
Members of the church of Amaunator were powerful political figures at the height of Netheril’s rule. Amaunator’s clergy were extremely hierarchical and rulebound.
It was eventually revealed, following the Spellplague that Lathander, the Faerûnian god of the sun, was an aspect of the long-dormant Amaunator. By the Year of the Ageless One, 1479 DR, Amaunator was worshiped both as Lathander and by his own name.
Amaunator is a careful and meticulous deity who makes certain that every agreement is written down, contracted, signed, sealed, and witnessed. An extremely lawful deity, he follows the letter of the law, not necessarily the spirit of it—unless the spirit is a great deal more to his liking.
He expects the same of his followers.
