Each level of Aegis Cave needs a certain set of unown stones to be in your treasure bag. For example, the Ice level needs ICE, then ROCK, and finally STEEL. All other stones are technically useless, but explode against enemies when thrown, doing 60 damage without reduction.
A random selection of Unown appear on each level, there is no specific one. You can look at the Recruitment List on your menu, to see what pokemon exactly appear on the level you are on. If Unown 'E' is there, just keep wandering until one appears. If not, then move on.
Well,not much of anything would be occured later....
You gotta defeat Unowns in the aegis cave
You must be talking about Aegis Cave. Check the stone marker that you are talking about. A word, spelled in Unown, will appear. In the dungeon-not where the stone marker is, but the dungeon part of Aegis Cave- are Unown. If you defeat an Unown, it may drop a stone shaped like itself. You must collect the stones that spell out the word on the stone marker. Then, check the stone marker. Close your eyes(in the game) when told to. The stones that you collected should react with the stone marker, revealing a hidden stairway.
The Unknown Dungeon (also known as Tag Mode) is a wireless feature of Blue Rescue Team which allows you to explore a dungeon when you encounter another person who has their Tag Mode setting on as well. When Tag Mode is activated and a link between two people is made, your leader Pokemon will go into a random dungeon and complete it like any other mission. For some strange reason, you will not be able to see your Pokemon navigate through this Unknown Dungeon and will only get the results of its endeavors. During your Pokemon's (automatic) exploration of the Unknown Dungeon, it may befriend/recruit particular Popkemon and find rare items which are otherwise unavaliable. Once its exploration it complete, your Pokemon will return and a message detailing what it has achieved will appear. Tag Mode can be activated from the main menu. Once it is turned on, you do not need to do anything else but wait as the linking and exploration is completely automatic.
When you complete any random missions after graduating from the guild in Pokemon mystery dungeon, you can go down into the lowest floor of the guild and you will meet team charm, from the special episode. You go with them to Aegis Cave, where you have to gather Unown stones to proceed and fight the bosses Regirock, Regice, Registeel and Regigigas. The bosses only seem to appear the first time you go to the cave, though. From Neonspectre
