Mangar's Tower  
 
Spoilers, Level 1

Look in the sewers for how to get past the gates. You will also need to get the Onyx Key from Kylearan. 
The magic mouth teleports you up to the next level, in an area that looks identical to the one you just left. Surprise... 

1 Beyond the lie
Before the slip
A passage north
Will fake a trip
And upward go
To evil's grip
Yet not an inch
Will seem to dip 
2 Ahead lies the Deathfield! 
3 Ahead lies the exit, oh faithful ones! 
M Perseverance in all things.
