Daedra worship: A poets guide for newcomers
We all know the Daedra, the Princes of much
they do have much power, but Nirn they can't touch
so when they want to speak, it is up to you
to give your life to one, and act for them too
 
Azura the soul star, of dusk and of dawn
she will bless you richly, on her you must fawn
she will love you dearly, she'll tell you no lies
unless you betray her, she's vengeful but wise
 
Boethiah the snake, of plots and deceit
he'll guide you in battle, keep you on your feet
with hammer or dagger, you will slay the weak
she'll make you the victor, unless you are meek
 
Clavicus Vile the masked, of power and pacts
he will grant you wishes, reward any acts
but always remember, to listen with care
his deals may seem to be, not always that fair
 
Hermaeus the vast eye, of knowledge and fate
if you desire wisdom, your hunger he'll sate
in his void so endless, the truth will unfold
but if you stay too long, your tale stays untold
 
Hircine the great were-stag, of hunting and game
succeed in his grand chase, and he'll give you fame
but his hunt is constant, so carefully see
that you stay observant, or hunted you'll be
 
Malacath the foul axe, of outcasts and spurned
those shunned by kings and queens, to this Prince they've turned
but don't expect mercy, if you choose to fail
for he shows no pity, no grace for the frail
 
Mehrunes the dawn of fate, of crises and shift
if he is unleashed then, his act will be swift
but Dagon is also, of floods and of flame
and Nirn as you know it, will not be the same
 
Mephala the spider, of death and of sex
she will teach you intrigue, the trusting you'll vex
but don't grow complacent, she cares not for you
and if she betrays you, your joys will be few
 
Meridia the star, of living and light
she'll give you protection, and blessings so bright
unless you are undead, or shield those who are
her light will purge you and, your friends near and far
 
Molag Bal the monster, of bondage and strife
you will learn oppression, how to own a life
the Harvester of Souls, is what some call him
so do as he says or, your fate will be grim
 
Namira the vile bat, of filth and decay
disgusting devotions, she'll show you the way
but few want to partake, where she is the host
the eating of others, is slandered by most
 
Nocturnal the raven, of darkness and night
through secrets and shadow, she will grant you might
but don't pretend to know, what lies in her shade
just keep thieving on or, your blessings will fade
 
Peryite the dragon, of order and blight
through sickness and cleansing, you will reach your height
but being his vessel, you'll have sealed your fate
no remedies for you, it is much too late
 
Sanguine the rose of blood, of passions and lust
your mind you will alter, and gashes you'll thrust
of fun and of parties, you will know it all
until it consumes you, and leads to your fall
 
Sheogorath the madman, of joy and of hate
in every emotion, he seems to partake
but you cannot fathom, where his mindset goes
his sphere may be order, I don't think he knows
 
Vaermina the serpent, of fear and despair
the pious may sidestep, her nightmarish glare
but if you fear omens, she's not worth the cost
it's best to avoid her, or you will be lost
 
Sixteen there are of them, known to you and me
who will grant you power, and gifts you will see
be careful who you choose, for their lessons are
demanding and toilsome, but can take you far
 
EDIT: /u/ludovician 's terrific response:
 
You know not the Daedra, you small, mortal fool.
Our power isn't granted or taken by rule.
If we wish to speak, we will find one like you
Who will say what we want to, and do as we do.
 
From Padomay's realm we derive all our strength;
We're change against stasis and ends against length,
Without us your life would be blissfully bored
No songs for your drinking, no prey for your sword.
 
Boethiah teaches the truth of your worth:
Without making impact, the fact of your birth
Is measured as dust, and dust is your name.
Killing is impact, and impact is fame.
 
Clavicus Vile makes a jest of a vow,
Of mortal words, empty as that they endow.
You see them as fixed. He shows you they're not.
Complacent, you asked, and deserved what you got.
 
Hermaeus shows you the maze of your mind:
You learn and forget in the way of your kind.
You see not the death of the knowledge before,
You are all in Apocrypha, searching for more.
 
Hircine reminds you no matter how fine
Are your clothes and your houses, your food and your wine
Your animal heart fights your noblest of aim.
You chase your own instincts: both hunter and game.
 
Malacath's Orcs may once have been Elves,
But everyone exiles a part of themselves.
Your shame and your longing, self-hate and regret:
Those parts of your nature you hoped to forget.
 
Mehrunes is destruction, the heart of the change
But with each revelation, familiar from strange
You burn up an innocent child without cause:
The adult you are slew the baby that was.
 
Mephala is hidden, her nature obscure
Just as you keep your nature behind your allure.
Only you know yourself. Your friends and your kin
Know nought of the secrets that hide in your skin.
 
Meridia's star's for the living alone
But her judgement is only as fierce as your own.
In your mind, only those that you know are alive
You care not if the million you don't know survive.
 
Molag Bal is a monster, but then, so are you
You bind with expectance and promises due,
With culture and norms, claiming others as yours
You enslave what was free, chaining souls, shutting doors.
 
Namira is filth and decay, and again
She's found in the natures of Beast, Mer and Men.
Reliance on others eats into their lives,
In interdependence her worshipper thrives.
 
Nocturnal is darkness, but also, she's luck:
With her, no predicting, and no bargain struck.
You smile on your fortune and curse at your harm
But each undeserved hope that you hold is her charm.
 
Peyrite is of sickness, and most of all yours
When you give up your hope and pronounce a lost cause,
For then the disease will quite certainly win
And the one called despair is already within.
 
Sanguine is your passion. The moment is now.
Why wait and delay when you'll die, anyhow?
You're mortal. You know that you're wasting away:
Forgetting tomorrow, you live for today.
 
Sheogorath's only the limit of sense
When there's too much to handle; the world too immense.
You know that your wisdom is flawed - even so
You make mad choices based on how little you know.
 
Vaermina is nightmare - your own inner fear
When you hesitate, seeing your failure draw near.
You fail without trying and then turn away
And your nemesis - you - lives another sad day.
 
You think you know Daedra? Little mortal, you don't.
I'd tell you to look in your heart, but you won't.
If you could, you'd have known what I've told you is true:
You don't choose the Daedra. The Daedra are you.
