The thing is, these lichen are actually found all the way through the game. You just never see them because they're on the roof. Any time you go into a cave, you never see any torches or lanterns or anything, right? And Ness doesn't have night vision goggles, or they'd be in the inventory. Clearly, roof lichen are the answer - intelligent roof lichen that used to live on the surface, soaking up light for millions of years, before undertaking a mass exodus to the unlit caves and the Lost Underworld, where they'll be releasing their absorbed light energy for another million years or so.

As for the distinction between the shining lichen of Lumine Hall and the ordinary always-on lichen found elsewhere, it's like the difference between a high school science teacher and a university biology professor: different pay scale. (HA! And you thought I would say something about respective intelligence levels!) Yes, those shiny lichen get paid more, so they flash and sparkle and read people's minds and stuff to please their boss/overlord, Electro Spectre. So when you kill ES, you're also killing the lichen's economic structure. Shame on you!

Gigon is the universe closest to ours. It connects to our universe through a portal. This portal is Ness' mind. Magicent is really the bridge between Gigon and Terra (our universe). In order to prevent Giygas from leading a full scale siege on Terra, Ness had to close off Magicent. With Magicent closed off, Giygas would be the only Gigite in Terra.

In order to destroy the bridge (magicent), Ness had to drain the energy from his mind and imput it in his soul. (There is a difference between mind and soul.)

The eight sanctuaries were what channeled energy to magicent, so Ness had to drain them. When he drained them, they stopped powering magicent, and all there power entered Ness' soul, making him stronger.

When the last sanctuary was drained, Ness' soul was overloaded with energy, and it all blasted back into magicent, making it stronger then ever. Magicent's power was so sttrong that it warped Ness into it. When Ness killed the Nightmare, all of the energy went back into Ness' soul, and Magicent was destroyed.

On the other side of Magicent, in Gigon, the Gigites tried to bore another hole in the fabric of space time, using the Psi Cannon of Lumeye. Lumeye's psi beams were so incredibly psychic, that they bore through the fabric of space time, but didn't leave a hole. The psi went into the past, future, and present, beaming through lumine hall. These Psi waves could read minds, so they read Ness' when he came through. Even after Lumeye is destroyed in 200X, they still go through lumine hall due to there time traveling abilities.

Using the light that occasionally shined upon the lichen, it was able to release a radiant glow. At first, the lichen just released a series of unintelligable symbols and letters and numbers. At the time, it was more like distorted aremaic. But as time went on, pyschics began being born. In this, they were able to sense that this particular lichen had something special about it. Eventually they were able to project thoughts, feelings and emotions into the fungus, but it did not understand.

Eventually, the lichen learned to read minds on its own and could shine on the wall what the people were thinking. Ness came, radiating about 10,000k normal background radiation from his psychic energies, and the lichen went haywire. It shined right into Ness' heart and mind and wrote out his words. Actually, because Ness is mute, he's been forced to bottle up his thoughts deep inside a very troubled existance (hence: Magicant.) and finally unleashed a long speech about every thought he's ever had. The game just edited it for length and simplicity.

After a long and empassioned speech about how much he hated beets, the team went on, and the lichen was alone once again. Now that it was entirly depleted of energy, the lichen perished, the only memory within the soundstone. It had done the only thing that destiny proclaimed it to do. That's it. Thank you.

Ahah! I have it! Lumine Hall is a prehistoric TV! Yes! Those poor savages had nothing to do, so they went to his big cave that had lots of pretty rocks in it! Then, one of the cro-mags thought that the rocks looked cool when he lit a fire in the cave. The he got really surprised when he started writing things using a laser pen dropped by aliens from the future, amazing his fellow neanderthals. To this day, he sits in Lumine Hall using his solar powered laser pen to shine it at the rocks making secret messages that nobody understands except Ness and his dysfunctional friends.

Okay, okay, so I'm crazy. But you know, Earthbound is a nonsensical game I think? So all of our theories are wrong and can never be proved because lithium batteries only last so long, and all our saved games will be lost forever and ever!!!*sighs* I'm done ranting for the day, thank you starmen.net!

(2. It reads the mind of the person with the biggest psychic aura. That is obviously Ness. Even if Poo was at level 99 and Ness was at level 12, Ness has much more potential that Poo. Therefore the wall would read Ness's thoughts.

(3. The wall is one of the new items made by the USA's Army. It projects people's thoughts onto a wall so they can tell what people are thinking. It runs on the electric waves in people's brains. They tested it and found the wall gave off large amounts of radiation, so they had to abandon it. They stuck it in the hole where no one would ever go. Ness and his teammates are not affected by the radiation because they are very strong. If they are not at least at level 40, you either cheated or are really good. If you are really good, Ness's mind would be strong enough to ward off the radiation anyway.

END

Many hundreds of years ago, the Tenda people roamed much of Eagleland's surface. They were a happy, prosperous people, but of course there was one guy who had to ruin the peace. His name was unknown, since he kept to himself, so people called him the Tenda Wizard. He was a bitter, senile old fellow, but wise and intelligent at the same time. He had travelled all over the world, learning magics from every corner of the earth. However, by the time he had settled down, he was very old. His home was in what is now Lumine Hall. It is said that one day, while trying to cook up a very difficult potion to read Tendas' minds, his cauldron exploded and the mixture hit all the walls of his corridor. Unfortunately, the Tenda Wizard was killed in the explosion, but his spirit stayed on, taking place in the walls. Now when travellers intrude onto his premises, he uses his final powers and reads the minds of others. Is it out of spite? Is it to embarass? We may never know...

However, some people thinks diferently. They say that Lumine hall really is... ｡No!, what they say is just nonsense, isn't it?.

It was perhaps these same aliens that made Ninten's grandfather, George, (earthbound zero) aware of humanity's psychic potential.

As for why they chose to communicate in this manner to Ness and his friends, I would speculate that their language is non-audible, and that they cannot broadcast thoughts to someone who's mind is outside their cumulative hive mind. So, the aliens devised a method by which letters could be formed by having certain members of their group illuminate their skin at certain times.

Yeah, thats about it

Now let me take a look at that brain of yours.

Basically Ness' stupid is so monumentally negativaly affective, that the lights that lumine hall is made of get dizzy and start flashing. This doesnt work on paula and poo cause they both have names that begin with p, for patrick star, as in spongebob squarepants, as in pinhead, so they are immune. Jeff, is so stupid he cant possibly go farther than rock bottom. Ness' PSI is what makes this gigantic field of stupid. Then, the lumine hall pushes them all out of the birth canal into the new and dangerous world.

It's so incredibly simple to explain, so I'm going to complicate it a bit.

Long ago, there was a wise man who sought the ability to read minds. After many experiments he still was unable to read minds. Now elsewhere, Spekkio, the master of war, observed this man's plight and decided to help him. (He was really drunk OK?) And so, using his cool magicky-type powers, he gave him a chunk of mold. The wise man simply complained to Spekkio that it was stupid. And so, Spekkio smote him. (Now you know what caused saturn valley, it's a big crater) Anywho, Spekkio decided that he'll just stick the mind reading mold on any random cave, and thus, lumine hall was made.

Fear the wrath of Spekkio!!!!

1. Ness's thoughts emit an ultrasonic frequency due to his PSI. The rocks in the cavern pick up the frequency and amplify it, which causes the wall to vibrate and then change color due to their strange properties. Kinda like a radio.

2. The little men in Ness's head use their tiny telephones to give the signal to the little men in Lumine Hall, telling them what Ness is thinking.

3. There is no Lumine Hall. It is just a group hallucination caused by the group's weariness.

4. A wizard did it.

That's all. Go eat pie, or whatever it is you people do. :P
