The enigm on the bottom left:

Auto tu dhon trox Zmv Eeozju Key
Gaxhb'q achb sdwtzufgfy ief vsxjsp iclfxv

Has the words "Auto Key", which is also a cypher method.
I tried using single letters as the key for this code, and with the letter "N", I get:

tu dhon trox Zmv Eeozju => "go deep into The Source"
Gaxhb'q achb sdwtzufgfy ief vsxjsp iclfxv => "There's more underneath the pretty covers"

... but I tried submitting different combinations with these words or letters, without further success...
