Ask a Derg

First, eating princess & knights are a myth. Humans have too little meat per bone. Second, fish and farm animals provide 90% of all dragon food. Third the most massive dragons survive purely off magic for sustanance (the other 10%). Lastly, a rare delicacy all dragons delight in is the elusive spineboar. They only materialize on an equanox wherd there is an eclipse. On a side note, dragons cannot get drunk or hungover so we drink mead quite often.
