The primary deity worshiped by the Yuan-ti of Tyr.
The Night Serpent came into being before recorded history, spawned from the feverish dreams of the first intelligent creatures. She subsists and grows stronger by feeding on the fears that plague the folk of the world. Her followers believe that Dendar is a harbinger of the end of things, which will come when she amasses enough power to consume the world. Another legend concerning her speaks of an iron door to the underworld behind which she lurks; when the time is right, she will tear it down, then eat the sun, plunging the world into darkness before she finally devours it.
