Heaven's Gate is a recurring location in the Dept. Heaven series, originating as the first stage in Riviera: The Promised Land. It is an area that links Asgard to the many gates to the surface worlds. Each gate is warded and some of them have a powerful guardian such as Marietta in Yggdra Union to keep surface-dwellers from waltzing into Asgard unbidden.
Heaven's Gate is visited twice. The first time, Ein and Ledah are traveling through it to reach Riviera. Much later, Ein and the sprites travel through it to find and confront Hector, the Traitorous Magus. During the revisit, the area is much darker in tone. This is the first and last stage of Riviera - The Promised Land, and appears in Chapter 1 - Angelic Advent and Chapter 7 - Within The Darkness.

Marietta, the Archangel guards the entrance to Asgard. It is here that the player is presented the option to seal away the Gran Centurio or pick a fight with her and wage war with the gods. If the player chooses the latter in the PSP version and defeats her in battle on a Hard difficulty playthrough, an extra battlefield can be played wherein the Royal Army advances to the Stone Lattice Area that previously appeared in Riviera.
The entrance to the heavenly realm glows with divine light. All coming to or from Asgard must pass through here. Beings from the mortal worlds are rarely allowed to see the world beyond here.
If the Wisp chooses to take Mellia's side at the end of blue path, another version of Scene 47 will take place. In it, Hector detects a disturbance of powers at one of the gates leading to Asgard and orders for the gate to be sealed away.Unable to return to Asgard with Ancardia in time and forced out into the human world, Marietta makes a decisive stand before the sealed gate against Wilmgard's knights and her counterpart. If Mellia is victorious, Heaven's Gate remains shut against her, which she sees as the gods turning their backs on humanity and leaving them at her mercy.
