Here's how the story of Equinelantis goes in Equinelantis: The Lost Equestrian Kingdom.
[After the Stuingtion logo is introduced, the films begins as a title comes up and says: "Years ago, when Equestria was smaller there was a great city called, "Equinelantis." Kingdom of Emperor Lunarlight, and birthplace of King Solar Flare]
King Solar Flare: Beautiful, isn't it father?
Emperor Lunarlight: Yes, my son.
King Solar Flare: [sighs]
Emperor Lunarlight: What's wrong?
King Solar Flare: If only Queen Starshine was here.
Emperor Lunarlight: Starshine, was a beautiful mare, my son. But she's in a better place now.
King Solar Flare: Yes, at least I still have my 2 daughters.
Emperor Lunarlight: Indeed. How are they doing right now?
King Solar Flare: They are doing just fine.
[The girls are sneaking up quietly to the adults]
Princess Celestia: Alright, I'll say when.
Princess Luna: No! You said, I could do it.
Princess Celestia: Okay, okay.
Princess Luna: But.... You can be my extra.
Princess Celestia: Sounds good.
King Solar Flare: I wonder what those 2 are up to now?
Emperor Lunarlight: You never know, son.
[The fillies tackle their father]
Princess Celestia: We got you!
King Solar Flare: You certainly did! [he lifts them off his back and hugs them] I love you 2, you know that?
Princess Luna: Indeed we do father.
Guard: Your higness! It's ergent!
[The Emperor comes out]
Unicorn staillion: Your highness, I hate to interrup you, but we have a problem!
King Solar Flare: [comes out] Father, what's going on?
Emperor Lunarlight: Something.
Uniron stallion: The Draconequuses are causing their troubles again in the feilds!
Emperor Lunarlight: [growls] Those morons just won't leave my kindon alone! Guards! Soliders! Get all of your men ready, if we can't reason with those draconequuses. Then it's war!
The Draconequuses king: War?!
Draconequus soldier: Yes, sir. The Emperor has declared war.
The Draconequuses king: Then it's war they'll get!
Draconequus soldier: But there is one setback.
[he takes the king to a group of draconequuses who are arguing]
Draconequus soldier #2: Ah your majesty. These guys beleive we should stop causing chaos amonst the equines, they don't want to go to war.
Emperor Lunarlight: It has announced, that we'll have war!
Emperor Lunarlight: Good! We shall go to war pretty soon!
[everyone agrees and leaves the castle grounds, then King Solar Flare walks up]
King Solar Flare: Father.
Emeperor Lunarlight: Yes son?
King Sloar Flare: I'm afraid to say this, but I'm gonna have to send my childern to a safer passage.
Emperor Lunarlight: What? But son, their our family!
King Solar Flare: I know, but I can't risk those beasts hurting them in anyway. It's the only way.
Emperor Lunarlight: You're right. Do as you wish.
[The Draconsequss walk up]
King Draconsequss: Alright, my friends. We will show those equines what happens when you mess with a draconsequus!
Emperor Lunarlight: Hurry, son! They're coming!
King Solar Flare: Don't fret father, I get the escape boat ready! Where are my daughters?
Princess Celestia: You're it. [she tags Luna and runs off]
Princess Luna: I'm gonna get you! [runs after her]
King Solar Flare: Cellie! Luny! I need you 2 girls here please!
Princess Luna: Okay, Father!
[the 2 head to where their father is]
Princess Celestia: We're in trouble.
[they come up to King Solar Flare]
King Solar Flare: Girls. There's a war coming, I have to take you somewhere safe. But I'm not gonna be able to stay with you.
Princess Celestia: WHAT?!
Princess Luna: But, father!
King Solar Flare: The guards are gonna look after you.
Princess Celestia: [weeping slightly] Do.... do.. we have t-to go, Father?
King Solar Flare: Yes. But here, take this. [gives them crowns] As long as you 2 were these crowns there's hope. I will see you 2 again. [kisses them both on the cheek] I promise.
Princess Celestia: Okay.
King Solar Flare: [to the guards] Keep them safe.
Guard: Yes sir.
[They got in a escapde pod and they fly away]
King Draconsequus: Attack the equines!
[The Draconsequuses attack]
[Equines attack the Draconsequuses]
[we veiw a the whole army of draconsequuses all dead and in ruins]
Emperor Lunarlight: It's over.
[Years later, and large bolt of lightning hit the ocean and made a tsunami wave]
Pegasus: You fool! You destroyed us all!
Pegasus #2: The wave is gaining! We have to warn Equinelantis!
Pegasus #3: Too late! AAAAAHHHH!!!
[several pegasi all fly into the city and the look-out staillion sees the wave]
Look-out stallion: Everyone! To the shelters!
[2 guards ring the bell as several of the citizens race for cover]
Royal Guard: This way your higness!
Empress Moonbeam: We're coming sir!
King Solar Flare: Mother, we have to hurry!
Empress Moonbeam: Son, calm down!
[then the city's saccride diamond shines a light on the empress]
Emperor Lunarlight: Son! Close your eyes, and look away!
[the Empress is then bonded to the diamond and a huge sheild surrounds the city. The whole city then sinks down as thw wave hits]
[40 years later]
Equine pirate captain: We've past the final marking lads. Now, to the portal, and Equinelantis.
Equine pirate #1: But Captain, have you forgotten that the portal is guarded by a sea monster that...
Pirate equine captain: ENOUGH! I'd slay many monsters for this book. Just like I'll slay you.
Equine pirate: #1: Yes, sir. I'm sorry, I was mistaken!
Equine pirate captain: Coward! SAIL ON!
Equine pirate #2: The storm is blowing harder, captain!
Equine pirate captain: Row you dogs! Put your backs into it!
[Then something roars]
Equine pirate #3: What was that?
Equine pirate #4: It's a sea monster!
Equine pirate captain: It can't be! Hold steady men!
[We then see a robotic tentacle sticking out and going back in the water]
Equine pirate #2: Is that a whale?
Equine pirate #6: Whale's having nothing like that!
Equine pirate #3: Where'd it go?!
Equine pirate #1: Can you see it?
Equine pirate #5: There's nothing there. [then a robotic tentacle grabs his neck and pulls him into the sea] GRAH!!
[Tentacles come out]
Equine Pirate #2: Ambush!
Equine Pirate #6: Behind you!
Equine Piarte #1: AAAAAAAHHHHHH!!!!
Equine pirate captain: [draws his sword] Do your worst! [a robotic tentacle grabs him and pulls him into the sea] BAAAAHH!!!!!
[Then a bolt of lightning comes out and blows up the ship!]
[Then the film says "Paramount pictures and Dreamworks pictures presents:" it shows a set of words in Equinelantian then it's translates into "Equinelantis: The Lost Equestrian Kingdom" then the title fades away and goes to black]
