Centuries ago, when Anck Su Namun and Imhotep were human, they fell in love at first sight and lived through the strongest, most maddening, and eternal of loves who no longer knew how to live apart from each other.
No matter how hard they tried to be away from each other, they couldn't, because the love they had was extremely strong and intense, which prevented them from seeing other people and when that happened, they became exaggeratedly jealous.
Therefore, they knew they had to pay the consequences for falling in love, and they were happy to pay, no matter what the cost.
But what they did not count is that, in their immense love, a third person would appear, who would do the impossible to separate them and that person is the Goddess Athena.
