Lathander (pronounced: /lɑːˈθændɛr/ lah-THÆN-der) was a Faerûnian greater god with a vast portfolio including birth, renewal, spring and youth, as well as athletics, self-perfection, vitality and creativity.

The Morninglord was symbolized by the rising sun, but rather than the sun itself was the god of dawn, which represented the potential of a new day. A god of hope and beginnings, Lathander's name was invoked at the start of new endeavors, whether sealing a new deal, or setting out on a new journey.
