The blind guardians are protecting the temple. Only the one who knows the answer to their riddle gets in.
How was it, again?
You always take us down
When we are in our prime.
Devour my sweet rewards
Yet I'll return in time.
A child of mine will rise
Out of his rotten bed.
Up from a hidden pit
Long after I am dead.
Little help?
Take us down means harvesting. child will rise from rotten bed could mean a seed sprouting something new. And sweet rewards means it is something sweet.
Don't get it
It's a peach, of course. You can climb back to Meriloft from Curtis' house.
