Gaia:Yes however you gave the world more than what i gave to you. The world has a future thanks to you.
Y/n: heh soooo what now?
Gaia: Now you rest young one you will ascend to the throne of heroes as a grand servant because of the deed you did. And don't worry i promise your legend will live on, I'll guarantee that.
Y/n: huh a throne for heroes, has a nice ring to it.
Little by little he's starting to disappear in a golden dust.
Gaia: Seems like you're ascending to the throne.
Y/n:Seems like it. Say hello to alaya for me ok, and tell zeus to tone down his hormones. I ain't around to babysit his other children.
Gaia: *giggles* alright alright now off you go.
As the young pendragon made it to the throne he sees other grand servants.
Y/n: So this is the throne huh? Seen better.
???:Hoh seems like another one has ascended.
Y/n: huh what do you mean?
???:Ascended you are one of us now a grand servant. A type of servant that it's job is eradicate a threat to the world and humanity.
Y/n: hoh so it seems. Oh by the way who are you?

Merlin: *confused* i thought the queen did not have a child.

Merlin: ah sorry shall i call you your majesty then?
Y/n: ah no no no don't I'm not royalty. I may have the name but i have no kingdom. What is a king without his kingdom? He's just another human being.
Merlin: Then i must be off I'm still enclosed in avalon after all.

Merlin: until then...........
Prince of knights.

Y/n:OF COURSE YOU PERVERTED WIZARD I HAVE EYES!
Merlin: eto it's going to destroy the world.
Y/n: i need to save gaia.....again.

*Meanwhile in chaldea when merlin summoned y/n*
As the servants watch their master struggle against tiamat the artoria faces is focusing on a certain perverted wizard.
Saber:what the hell is merlin doing?
Romani: he is summoning another grand servant but it's still a gamble.

Mordred: it did not work!?
"*Bright light*"
Salter: what the hell!?
"Saber servant y/n pendragon have heard and answered thy call. Huh? Merlin what the bloody hell did you summon me for?"
"Ah your highness see that beast there."
*Shocked saber faces*
Mordred: what the hell is going on why did merlin call that saber "your highness"? Did you have another child huh father?
Saber: n-not that i know of.
*Back at kur*
Y/n: *sigh* well then I'll join the scrimmage.
*As y/n attacked the smaller minions gilgamesh arrived.*
Gilgamesh: seems like you've settled the score ritsuka fujimaru. Then let this next attack be a parting gift.
*As gil said that y/n dropped beside gil.*
Y/n: hey mind if i also deliver the final blow.
Gil: heh can you keep up mongrel?
Y/n: huh? Can you?
Gil: alright then *summons EA* i shall perform this final blow as a parting gift to you.

"As the blow was delivered tiamat was killed and uruk was saved"
Gil: seems you can keep up mongrel.
Y/n: seems like it.
*As he said that he starts to disappear in gold particles*
Y/n: looks like my time is up.
Gudao: will i ever see you again?
Y/n: that i do not know. But whenever you look at the surrounding either it snow or tree think of that as my presence.
Mash: it's nice to meet you even if it's just a short time.
Y/n: yahh it's nice to meet you too. Here *gives a plate of armor.* If you ever need me summon me using this as catalyst.
Gudao: thank you.
Merlin: your majesty it's time to return.
Y/n: yeah let's go perverted wizard. Until then master of chaldea.
