Just a basical question, many people refer to AE and something about a loveletter. Has this something to do with CHIM, something I understand very little. Can somebody explain? What do these terms stand for?

"AE" is a connecter. If I remember right, it means something like with/and.

Quote from the Translation Dictionary:

CHIM
Meaning: An ancient sigil connoting 'royalty', 'starlight', and 'high splendor'. As with most characters of that dangerous language, the sigil CHIM constantly distorts itself. Those scholars that can perceive its shape regard it as a Crowned Tower that threatens to break apart at the slightest break in concentration.
Origin: Ehlnofex
Usage: None Given
Source: More on Psijic Endeavour and The Thirty-Six Lessons of Vivec: Sermon Twelve
Reliable: Yes

In context, AE is found in Elhnofex languages denoting the equivalence of two nouns.
'is' or 'and'
Vehk Ae Seht Ae Alma
Vivec is Sotha Sil is Almalexia
Vivec and Sotha Sil and Almalexia [are all one]

Used on its own, it represents the connection between all things: the totality of the universe. I believe it has been used to describe the process of dead souls returning to the greater universe that spawned them, then the Dreamsleeve takes care of them.

Chim involves fully recognizing the indivisible nature of the universe, but holding onto individuality despite the horrible truth that you have none. This requires considerable badassery, or as the Chim sigil puts it, 'royalty.'

Is AE referring to Anu/IS?

It refers to the two opposites together. So it refers to the Aldmeri vision of Anu (which refers to the entity existing before the split into the opposite forces.)

So Ae is the opposite of CHIM, AE coming from the vision of most Aldmer (everything is one totality, lorkhan is a trickster, creation is bad, this world is bad--> negative vision), and CHIM states that you also have an indivituality, so don't nessicarily have a predestination you can't escape. -->positive vision on the world, supported mostly by men.
Am I right?

i'd say not really. as it was stated, AE is duality, the split existence of our world, subdivision; though it also hints at unity through its role as an Ehlnofex connector. CHIM does not deny AE and actually plays into it - CHIM is about realizing that everyone is the same single being but still able to retain individuality after that. to achieve CHIM to to overcome split existence (AE), but they do not contradict each other, as everyone still continues to live within the subcreated world.

not sure how clear that was, i got up 10 minutes ago.

one last question about this: the Tower means the same as CHIM, doesn't it?

Chim is the secret that lets you holds the realisation of the Tower together.

The Tower is the cosmic concept of individuality and selfishness. It is also the "shape" of the Chim sigil.

I'm not sure linking to a Tarrot card without explanation is much help to anybody. Without explanation I'm not even sure it is the right card, http://www.aeclectic.net/tarot/basics/tower.shtml actually seems to come closer. The Tower symbolizes the lies he, (the fool, the Aurbis, the priest) held about himself, everything he created before enlightenment. It's destruction, letting go of those things, stands in for being able to see your self as a part of it.

Though, I could also make arguments to add a few more cards to the mix as the Tarrot story seems to have a longer, more phased concept of transcendence.

I thought he was making more of a "perspective" reference rather than a direct reference to what the Tower represents.

Being Divine Comedy ignorant (sadly and ridiculously), I don't really have an idea of how that's CHIM that I'm really confident in.

How much of this Ehlnofex is actually known? All I can think of is:
ALTADOON - weapon
CHIM - a sigil canotating royalty and starlight
AE - discussed in this topic
Is that all?

Fair points.

By the hanged man card I meant the Tower as an Activity, so to speak. You might say the hanged man is ascending the Tower, or what it means to ascend the Tower. If I found a good picture of Odin on Yggdrasil, I could have linked to that for a similar effect.

The CHIM picture was intended to suggest lucid dreaming, which is a way of pointing towards CHIM.

And the very nature of lucid dreaming is why I didn't offer a full explanation for the pictures (and still haven't!).

The sleeping Christ figure and the clever use of the word "elucidate" did make me thing of lucid dreaming. Sadly, I didn't jump on that idea. The depiction of god, the serpent, and that three headed...thing threw me off a little.
