A Sunspeaker is an Efreet member of the Sunspeakers faction, one of the two factions of followers of Ra. Even decades after the War in Heaven they maintain their sacred duty of protecting the lighthouses and keeping them lit to guide travelers through the sands and providing a place for rest and respite from the dangerous desert.
You can find Sunspeakers inside of any lighthouse in Atum.
Sunspeakers are neutral entities but once provoked or attacked they will become hostile to the player.
You can trade relics to a neutral Sunspeaker by right-clicking them while holding any clean relic.
You can also purchase items from a neutral Sunspeaker with atum coins by right clicking them without holding anything.
