Oblivion Gates are the gateways created between Oblivion and Tamriel. They are magical portals that facilitate travel between the two planes. They are made by Daedric worshipers in an effort to essentially merge the worlds, allowing the Daedra to roam Tamriel and rule it.
Closing Oblivion Gates is one of the main tasks in The Elder Scrolls IV: Oblivion. During the Oblivion Crisis, all of Tamriel was attacked by Mehrunes Dagon's Daedric army. Oblivion gates opened throughout all of Tamriel, and many cities were destroyed. Martin Septim summoned the Avatar of Akatosh and defeated Mehrunes Dagon during the Battle of the Imperial City, ending the Crisis and preventing more gates from opening.
Oblivion Gates appear pseudo-randomly throughout Cyrodiil, based on the player's progress along the main questline of The Elder Scrolls IV: Oblivion. There are 100 distinct locations where a gate can appear, and as each gate is closed that particular location will never spawn a new gate. (Gate re-opening can be turned on via console commands, but is off by default.) However, no more than 60 separate gates will appear during a single game, including 10 gates which always open in designated spots.
There are two gates that open on top of wayshrines. The first opens and completely buries the Wayshrine of Mara northwest of Anvil. The second one opens on top of the Wayshrine of Kynareth east of Skingrad at the top of a steep hill down the gold road, breaking it in half, although this wayshrine can still be used by activating one of the two halves.
When entering an Oblivion Gate, there are several exterior map templates randomly chosen from, as well as several interior maps for the towers and caves, which allows for different map configurations for each gate. The ten guaranteed gate locations lead to a specifically chosen Oblivion map; five gates lead to a specific one of the random worlds, and the other five have a custom Oblivion map with random towers.
When closing gates, It's worth noting that followers cannot enter them; they must be closed alone.
These gates always spawn in the same location, and are triggered as soon as a specific part of the main quest line in completed.
Only three gates that are required to complete the main quest. These gates are:
- Kvatch Descendant Gate: Opens outside Kvatch as soon as the Hero leaves the sewers. Leads to the unique Kvatch Gate world.
- Bruma Gate: Opens outside Bruma after delivering a Daedric artifact to Martin. Jauffre sends the Hero to close this gate. Leads to the unique Bruma Gate world.
- Bruma Great Gate: Opens in a field southeast of Bruma, after arriving there with Martin. (Note that other Oblivion Gates open during this quest, but those cannot be entered). Leads to the unique Great Gate world.
The remaining gates are part of the Allies for Bruma quest, one per city that may send allies. These open as soon as the Hero steals the Mysterium Xarxes from the Dagon Shrine. For each city, the nearby gate must be closed before the Count or Countess will risk sending their soldiers away to Bruma:
- Cheydinhal Gate: Leads to the unique Cheydinal Gate world (and The Wayward Knight quest).
- Anvil Gate: Leads to a world with the Sigil Tower atop an unclimbable mountain, which requires traversing two sets of tunnels to reach.
- Bravil Gate: Leads to a world with a single war gate between the Oblivion Gate and Sigil tower, which is opened from one of two peripheral towers.
- Chorrol Gate: Leads to a world with six "natural disaster" towers and four war gates.
- Leyawiin Gate: Leads to a world with a dead horse and a ruined bridge just inside the gate.
- Skingrad Gate: Leads to a world with two side towers and retractable bridges.
- There is always an Oblivion Gate near Fort Sutch, which opens at the same time as the city gates; this gate randomly leads to one of four Oblivion worlds.
In addition to these ten gates, up to 50 out of the 90 remaining gate locations will spawn a gate as you progress through the main quest. These gates do not spawn all at once, but appear to spawn as the player nears their location. For example, one could pass an Oblivion Gate at one location, reload an earlier saved game, and no longer find it at that location. Once a gate spawns and is closed, the dead gate remains present for the rest of the game, and no other gate will spawn there. (Until the end of the main quest, Oblivion Gates can reopen).
The number of gates, and the odds of a gate appearing, depend on how much of the main quest line has been completed. After rescuing Martin from the Kvatch Gate, up to 25 random gates will open. When nearing each possible location, there is a 25% chance that a gate will spawn. At the same time that the fixed city gates open, the number of possible random gates increases to 50, its highest point. In addition, there is now a 50% chance of any given gate location spawning a gate. After retrieving the amulet of kings from Paradise, the number of gates drops to 20, with a 20% chance of a new one spawning. Note that the maximum number of open gates also includes dead gates that have already been closed; that is, if the player has closed more than 20 gates by the time they return the amulet, no more will spawn.
Upon finishing the main quest, the maximum number of open gates, and the odds of a new gate opening, both drop to zero. From this point, new gates can only be opened with console commands.
