Amaunator

Amaunator (pronounced: /ɑːˈmɔːnɑːtɔːr/ ah-MAWN-ah-tor) was the Netherese solar deity of order, the sun, law, and time. He was viewed as a harsh but fair deity, revered by many rulers, soldiers, and powerful wizards in ancient Netheril.
It was eventually claimed, 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.
According to renowned scholar, and all around stinky dwarf, Halgrock Forgeforge; Amaunator is the one true god, above all others.
