No, but if you want the regis (apart from regigigas as it is not in the game) and mew you will have to.
Do you mean Buried Relic? Buried Relic has 99 floors in total. Good luck.
After you have completed the story, finish stormy sea and after a few days a PKMN news issue will appear speaking about a new dungeon. After reading this go talk to Lombre, them talk to Shiftree, and you will unlock the buried relic for exploration. And how if you are all ready way further in the game? :( The Answer Above is all true, however there was a little error 1: Finish the game 2: Talk to medicham outside your house, then talk to lombre and unlock stormy sea 3:beat stormy sea 4:make sure your post box is empty and i mean EMPTY. 5: Just do a dungeon (Like tiny wood but it doesn't really matter which dungeon you do) and if you check you mail box, you wont see the normal options, it will just come up with 'Buried Relic Discovered' if this did not happen, keep emptying your mail and just beat tiny woods. (This might take a while if you haven't catched up with your mail from the start like me ;D ) Hope this Helps Pokemon Master Amz Wait I can't delete my mail !!! AwsomeCyndaquil O.K I got the one for buried relic and did what u said Pokemon Master Amz AwsomeCyndaquil

You must buy southern island and then a cutscene will happen. Buried relic isnt compulsory however. Also, you must recruit zapdos articuno and moltres to unlock silver trench in the future...
