Becoming Death
Amara and Chuck went to work in the Bar. Taking her true form of a dark cloud, the Darkness used the affinity between the abundant primordial basis of dark matter and her essence to summon a small portion of that to her. Meanwhile, God, taking his true form of divine light, manipulated time across all Creation to almost, just almost, a standstill. Once the two primordial entities finish with this work, they will have done so in less than an hour of normal time.
From her true form, the older sister said, "Let there be a Lesser Darkness, a Dark Herald."
As the intensive work progressed, the Destroyer gave form, power, and insight to what was becoming a new being. So great was the power received that what was becoming a new, wingless being could be neither banished nor bound, and held more power than four or more times the firstborn son of her younger brother. So great was the resilience of its life force that part of it had to be dispersed from the onset into the very fabric of the primordial basis of dark matter. The Creator was impressed at this, what could have been a primordial creation but was far greater than such. The insight provided was of similar magnitude.
Once all that power and insight was received, the form that emerged truly was a Lesser Darkness, a dark cloud like its creator. The greater dark cloud and the divine light then assumed human form, so that the lesser dark cloud could mimic that and assume a human form of its own. Not long after, it imitated its creator and assumed the form of an adult woman.
"Mother… Uncle…" said this adult woman.
"My creation is good," Amara smiled.
"Like you said to me, what you've made is beautiful," Chuck added, releasing his hold on all of time so that it could resume its normal speed.
Amara smiled, then turned to her daughter and asked, "Have you decided upon a name for your physical form?"
"Sefira," answered the daughter, "For I am a wise emanation."
"Very well, Sefira," concluded the Darkness, "Henceforth your purpose is to enforce the Natural Order. You have become Death."
As her daughter nodded, God declared, "It is good."
