The guardians came to sit down at the dining table. They looked at the colorful food served on the table and were at a loss. They have seen good food in the god realm and it is delicious to them however, they have never seen such neatly served dishes. 

The gods, do not eat much, and neither are they eligible to look at the gods. The food they were served had never looked so delicious. However, even after being fascinated by the food they did not move. Willian asked them, "Is there any problem?" 

The three of them exchanged glances and Oz said, "Lord, we are not allowed to take off the hood of service in front of anyone other than our brethren. Please forgive us, but can we take this food away with us?"

Willian was surprised but he quickly nodded, "You can. Please help yourself."
