You turn left, right after you take a couple of steps everything goes white with fog and a looming shadowy figure speaks in a low grumbling voice. You recognise a shadow as something you didn't even know actually exists. A chimera!
'If you wish to continue on your path, a riddle you must answer. Answer correctly and you shall pass. Fail to do so and suffer the consequences.'
You were about to politely decline and weasel your way back but the chimera starts with the riddle:
'A rooster flies up to the top of the roof with the wind blowing from the south, when it lays an egg. On which side of the roof will the egg roll, tell me this, left or right?'
