Note from the author :) :
Thank you so much to azia0117 for sharing her thoughts to the theory! You may be correct about Kul'zak and Esmund being brothers because of Zane and Garroth . I'm sure to analyze the idea at the conclusion of this theory!
Thanks also to @aarmaufan12268 for adding the book in your reading list. Your enthusiasm for theories are awesome!
Thank you for all the support!

Previously on the theory : We talked about their appearances and the questionable giving of powers to the 5 other guards by Lady Irene .

Now , let's talk about that power . The Relics.
Also . Lady Irene has a SISTER?!?
What even! Lady Irene has a sister..
Who could that be and why didn't she helped Lady Irene at all in this ..
Umm.. "Defend the world's evil" cliche .
She might be her bad sister banished by Irene herself . I don't know where.
You probably guessed how I got this.
Celestia and Luna from MLP.
But hold ye ponies. We're not talking about the two "Supposively Divine only" sisters today.
We're talking about the Relics.

The Relics are super duper powerful runestones (RIP Rune and Dreams of Estorra) and gives you the powers that Irene has too.
But as said in the meeting of the 1 now 6 newly proclaimed Divine Warriors ; these relics will give you a burden.
Immortality.
And I mean , Wow! Immortality , that wouldn't be a burden . Everyone wants to become an immortal!
It will be amazing to be immortals the like Greek Gods do!
"Hm. That doesn't seem so bad." ~Kul'zak even said...

Cool as all... But if you remember , Immortality is the same thing Irene has in accompany with her extraordinary JESUS powers.
Sorry Christanity . Don't mean to offend you and all... :(
(Oh. And hahehiHOHOHOhu!! Late MERRRRY CHRISTMASS!!)

But as you known , Immortality makes you live forever and that means you can see the future of everything and you get to keep all your memories while you live longer.
You won't expect death.
Although there's one slight problem that Irene shows in the MCD storyline.

Lack of Love and Emotion.
Because of her living so long , she loses her feelings. She shows the effects of people who gets depressed and abandoned.
That's for one single reason , Love ones. That why she said this line ,
"-The cost could be deeper than wounds could ever heal."

She lives long but her love ones DON'T . Concluding her missing those that she was with during her whole lifetime.
Yeah , you get to see your grand daughters and grand sons or even the longer term but , it just seem to be obscure to see them die with your very own eyes.
It's like you're a ghost that no one sees . It's like you're dead but not really.
For Irene to be a normal person ,
It was hard for her to be a mother , a sister... , a friend , a family member.
Immortality was a curse for her.
Not like the Greek Gods , Irene was always lonely due to the fact that the
Greek Gods' families are all immortal but for Irene
All she wanted was Love and Care , to support her own family but she couldn't because she had to choose .

The World or Her Loved Ones .
She chose the world.
Not for her family but for the entire world's families.
That is how loving Irene was.

*claps* Boy , Now that's what we call sacrifice!
Irene , you are the Matron!
*badum tss*

But now , not only Irene has to suffer but also her 5 other guards who wants to serve her.
They are also normal people with families but with the same fate as Irene had , they chose to defend the world too.
Now they're one big 'Greek' God family , all with the same conditions.

Let's look on the relic's REAL powers now.
It was said that,
"These relics are incredibly special. They are a part of you , in more ways than you know." ~Lady Irene

And what she ment as a part of you is actually how the relic will reflect on their destiny.
"At some point in our lives , we'll be tested. And these relics will have a major part to play in the future." ~Lady Irene

This is where the titles come in. Representing each of her five guards with a name to their relic.

Esmund , The Protector
Menphia , The Fury
Enki , The Keeper
Kul'zak , The Wanderer
Shad , The Destroyer

Very peculiar names .. Even Irene's relic is named
The Matron

That all doesn't makes sense to them when they first accepted it.
But the truth is it did made a big impact to their lives after that day.
Let's examine the names first.

Before anything , you do remember that they were guards.
So maybe this is how Irene labeled each one of them.
By their guard positions.

Being
Esmund , The Head Guard making him The Protector since he really likes Irene and will protect her and his realm.

Menphia , The "MVP" of the guards since she was also described by Irene as a strong warrior. She might have gotten all the great kills..

Enki , The Wise person of the guards or maybe the stragegist since he holds books all the time...

Kul'zak , The Guard who always walks off or possibly the Spy since .. Um.. He has a blind eye.. What?!

And

Shad , the Underdog..
Aww.. Shad.. Although we always have these cliches where the highest one versus the lowest one fights for only one person..

Still how I labeled them doesn't makes sense so let's look at it in another way.

The real names. The fates of one another.

Esmund , The Protector because possibly he tried to PROTECT Irene from Shad. He thought about the idea of killing Shad in the first place anyway to defend Irene's emptiness... Which wasn't correct..

Menphia , The Fury because possibly she went FURIOUS on a big fight after or before killing Shad happened . Giving The Fury she is , kills herself? xD

Enki , The Keeper because possibly he might have KEPT secrets about him loving Irene.

Kul'zak , The Wanderer because possibly he might have WANDERED off somewhere and never came back.

And

Shad , The Destroyer because possibly he decided to DESTROY himself to destroy other lives..

Still makes no sense . But most of them were correct .
On that , maybe that's how the Divine Warriors seperated and died on other fields although on the illustrations that showed up while Hyria was talking about Irene in episode 100 of season 2 , it showed that all four tombstones were on a hill with Irene standing besides them. So maybe they all did died and were buried side by side.
But their souls when they rebirthed traveled to different areas of Minecraftia. From the Gal'ruk region , to some areas in the Ru'aun...

But what if I tell you that their relics' fates weren't actually in the time of their living with the big Shad fight happening.

What if their fates will happen on their
DESCENDANTS?
What if TIME repeats on THEM and that the specific time line of history repeating will start on
APHMAU'S LINE ; the current storyline/timeline of MINECRAFT DIARIES...
The six Divine Warriors Future is happening NOW on MCD.

Oh yes , this is getting real intense.
Gotta settle down and chill..
Coming up next , The Descendants..
