"First!" A boy called "First where are you?"
"Over here Third!" Came the answer, "To your left!"
"Oh! First here you are! I was looking for you. But where is everyone else?" The boy said.
"The others are just outside, Brother. would you like to go see what they are doing?"
"I would love to, First."
"Amazing. Then let us go, Third."
...
Three Years Later:
"Ah... Here they are Third!"
"Oh! Second, Fourth! Where have you been? It took us a while to find you, you know."
"We were just out taking a walk, my brothers. It is nothing to worry about. how have you been? I noticed you slept in a couple years, First."
"Ah... Sorry about that. I had a hard time going to sleep last night."
"Oh... well are you sure you are okay? Having trouble sleeping isn't just a mild issue for us like it is for mortals."
Do not fret, Second. It was just some... Worries for the future. But that is enough of that. How has your century been going, Fourth?
Seeing that First was not going to speak anymore on the matter, Second pursed her lips and turned her attention to Third.
"Third, How have you been?"
"I have been in good spirits, Second!"
"Oh that is good to know. Ah! Third, that is quite the interesting creature over there. Would you like to investigate it?"
"Sure, I am interested, It is one I haven't seen before."
...
Five Days Later:
"You were right, Second! it seems to be a new type of bipedal creature! It seems insistent on calling itself..." Third listened closely "A human! Now isn't that interesting?"
"Yes it is, Third. But come close. I wish to ask you about something"
"Very well, Second. How can I be of help?"
"Oh nothing much. I just wanted to know if you had noticed If First had been acting strangely?"
"Hm... now that you mentioned it, He did seem slightly melancholy when he woke up." Seeing Second frown slightly while pondering what that meant, Third spoke, "But enough of that Second, let us go back to the others. I want to play with Fourth!"
Giggling, Second said "My My, you are still a youngling, Aren't you!"
"No I am not! I am a full 5 millennium old! I am super old!"
"Yes, yes you are" Second said, still smiling "Now let us go back to the others. I will race you there, and if you beat me, I will let you and Fourth play with each other an extra 10 years before slumber!"
"Really? Deal!" Third said, already getting ready to run "Ready, Set, Go!"
...
Fifteen Years Later:
"First, come inside" Second said, well also motioning to the youngers that their playtime was almost up. "What ails you?"
"Nothing Third Sister, I was just plagued by unhealthy thoughts momentarily."
"But that is so unlike you, First. Would you mind telling this one what these thoughts are? I would love to help you with them."
"Very well Second, I will tell you. Recently I have been feeling... Purposeless. This world has no need for us, and it will continuously evolve. we have already seen it begin to happen! there are so many new species and societies that I couldn't even dream to think of, and they are already forgetting us. We have already created a perfect system of existence. We are not needed anymore"
Surprised, Second replied "Well, First, I can see where you are coming from, and it would be a lie if I said I had no such thoughts myself. However, I am sure that a reason will show itself eventually, and we also need to take care of the youngers. Where would they go if we were to leave?"
"You make a good point, Second." First said, smiling. "I will remember this if Such thoughts surface again."
And a couple days later, they decided it was time for slumber.
[A/N: I thought it was necessary to explain this. Being primordials, they live on a different timeframe as other creatures do. A millenium is a year, A century is a month, a year is a day, a month is an hour, etc. also, their names references the order in which they willed themselves into existence.]
