According to legend, the king spent the first watch of every night with a woman thought to represent a Nāga in the tower, during that time, not even the queen was permitted to intrude. Only in the second watch the king returned to his palace with the queen. If the Nāga who was the supreme land owner of Khmer land did not show up for a night, the king's day would be numbered, if the king did not show up, calamity would strike his land.
