Not the one at Kvatch, but the ones found randomly out in the wilderness do.
But if you have completed the main quest they never open again
The Gates of Oblivion was created in 2002.
No.
There are no living orcs in Oblivion in The Elder Scrolls IV: Oblivion. However, there are many orcs throughout Cyrodil that you can find while not within one of the Oblivion gates.
there are alot of other gates you have to look for them
you get one by killing sum bandits in bout any tomb.......
Hate to break it to you but umm I don't think there are any gates like that except in Oblivion.
Defeating Mehrunes Dagon will close the Oblivion Gates, but you could still visit Oblivion afterwards if you do Peryite's daedric quest.
You may try lowering your difficulty setting.
The daedric realm, Oblivion, is a different plane from the one in which the continent of Tamriel is situated. Creatures can travel to and from Oblivion through Oblivion gates, so presumably that's how daedra would travel to Elsweyr. (Note that this can not be done in any unmodded game).
Im not quite sure what your asking, but the guardians of oblivion are the daedra, ( the guys who wield big weapons and run around wearing daedric armour) and most of the creatures in the oblivion gates ie: scamps, clanfear, daedroths, astronachs ect...
umm i would say you are one loner gamer who spends ALL of your time playing oblivion. or you are crazy ?? go get a psychologist :D
The Olympus Coliseum is a world that is eventually unlocked through progression of the storyline. In Kingdom Hearts, it is located in between Traverse Town and Deep Jungle. In Kingdom Hearts II, Olympus Coliseum is located right next to the Land of Dragons.
