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... 0x4e84
