Death Gate

Lucifer skipped merrily along the barren wastes of the land of death. His blonde hair billowed behind him as he strode through the landscape. He held his hands behind his back as he walked, whistling to himself as he went.
Eren followed closely behind, struggling to keep up with the flamboyant reaper. "Lucifer." Eren called out to him. "Hold up."
"Yes?" Lucifer answered, turning around to face him. "Those reapers that watch me... why are they so different from each other?" Eren questioned, curiosity burning inside of him.
"What do you mean?" Lucifer asked, cocking his head slightly. "The suits versus the armours." "Why is it that they look so different? And they were all separated from each other."
Lucifer hummed thoughtfully for a moment before responding. "Ah I see what you mean now. Well... to put into human terms, they are of a lower status. Like corporate and blue-collar workers."
"Ooh... So, there is like... a social hierarchy?"
"Why?" Eren asked, curious about Lucifer's answer. "Well, that is quite complicated. You see, all goes back to a time from way before I was but a mere twinkle in the universe." Lucifer finished, skipping merrily once again.
"Stop. That's not an answer." He called out to him. That answer was less than a response for of a side-step.
"You are very inquisitive today, aren't you?" Lucifer teased playfully.
"Yes, because I want to know why you managed to be able to flick your hair all day and Charon gets to watch a line for all eternity. It seems unfair." Eren asked,
Lucifer stood silent for a moment, contemplating his words. "Hmm... I suppose it is a bit unfair. We can't all be me now, can we?" He chuckled softly.
"But alas, I shall put aside my vanity and divulge the information you so seek." Lucifer declared, taking a seat on the ashen sand.
Eren joined, legs crossed, ready to listen.

Firstly, above all is death. He or they or the void... I don't know. Any way IT is this land, everything around you. The sand, the sky, all the energy within us, it's all death. We are propelled by its energy.
That is the head of our structure.
Next, the three main pillars of Death are Judgement, collection, and sovereign.
Sovereign is headed by Azazel. Who you thought was death is in fact, a physical manifestation of death itself. He oversees all, deaths voice, it's reason and its power. He is the only one who has power over all.
Collection is headed by the deviously handsome Gabriel. His duty is to manage all the reapers. How many are sent out and where, he must also ensure they don't go rouge and deals with any internal conflicts. I'm his favourite.
Then we have judgement, headed by the intimidating, slightly sexy Anubis. His job is to pass judgement on souls, observing their life's. Sorting them and sending them on their merry way to the beyond.
Below them we have the second tiers. Under Collection, we have reapers like myself. We must Look gorgeous at all times. As we must be presentable for those souls we collect and pass to them on for judgement.
Below Judgement we have sentinels, like Charon. They serve to maintain order in the land of the dead, preventing souls from wandering or getting lost. Or on the rare occasion, operating as foot soldiers for Azazel.
And lastly, my special little dove. The third tiers. Harbingers, warriors that work within the world of the living. An extension of death and all his machinations. That will be you.

Lucifer finished, beaming happily. "So, there you have it, the roles of us reapers. What do you think?"
"Seems... simple." Eren replied. "But you didn't tell me how roles are chosen or what determines the social order."
"What, you want me to explain that too?" Lucifer groaned, throwing his hands up into the air dramatically.
"Yes. Please." Eren responded curtly, watching him carefully.
"Luck."
"Luck?" Eren repeated, not quite understanding what Lucifer was getting at.
"Yes. Luck. You see, we do not decide on our own what role we are assigned. Azazel chooses it for us. Some are more fortunate than others."
"But... We all get the same choice."
"Join or move on."
