First, what I did was I went into notepad and just typed the entire text into a single line.
almonisdfrerroroountatnelgmmsiuniiel
Looking in the middle, I noticed this part
almonisdf
rerroroountatnelgmmsiuniiel
If the first R, the second O, and the last T were to be changed were to change to a T, an M, and an I (respectively)it would spell Terror Mountain.
Well, look at the spacing:
rerror
oounta
tn
They are all exacty 6 characters apart from each other.
And as you can see, on teh 6 x 6 grid, the column where those three letters that need to be changed are contained it, it also contains the letters T, M, and I in that respective order. Quite cowincidentally, the same three we need and in the same order.
So, if you take the fourth column and move it up two spaces, you'll get Terror Mountain reading across the second to fourth rows.
Two red herrings (or at least 'clues' that would throw people off):
1. Talking about Illusion, then including the letters for Illusen's Glade in the puzzle. This was just to catch anyone who was randomly putting letters together off-guard.
2.

'I an' ??
Silly TNT, you should know better than to only trust spellcheck, you gotta proofread too!
