Answer:
Scythe of darkness, Shadow’s light. Guiding eye of thirteenth sight.
I have one eye. See near and far. I hold the moments you treasure and the things that make you weep.
My prefix is food. My suffix is rude. My infix comes in rounds. I keep you off the ground. What Am I?
I have four legs but no tail. Usually I am heard only at night.
What do you throw out to use and take in when you're done?
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
