Well,I got a old theory about it,Simple as it sounds,Imagine each power you have,Is a password,And each rune is a letter for that code,So each time we get a rune,We get a letter,Then the character memorize it(To prove,Each rune got random letters on it if you look closely),Now when you collect enough letters,You get to know a new power,Like a password Don't lose me now,Since here it gets a bit harder.

The Charcater memorize it,Then it allows him to say it over and over again,And each time he does think\say it,It happens,Since he has the mark,Non marked people wouldn't see these letters.(To prove that,Each time you use a power,there is a sound,Whispering(Hold the ability)).

Got it by far,No?,Yes?

Here comes Corvo part,Delilah learned how to lock a specific channel in the void,She locks Corvo one,Thus leading him to losing all of his powers,And later on the memory of each specific letter he required to use a power,I hope you follow me,The outsider unlocks it,But Corvo have already forgotten the passwords for each one.(I know it's complicated,To put it short for you guys,Each rune is a letter from a password for a certain power,You collect an amount of letters,And then you figure out the password,And you use it,Delilah basicly locked Corvo connection to the void,)
