I'm sorry to drag you all into this.
But the Fishermen can't think that Atlantis was involved.
Atlantis does not command the armies of Xebel. I do.
And the Brine Kingdom
has not forgotten its debt to you.
You may count on us always.
Something happened to me.
When I touched that black trident.
Why is he even here?
He should be on his way back to prison.
We should hear what he has to say.
I made that mistake once.
That's why I know he can't be trusted.
And he cut off my claw.
This thing took a whole year to grow back.
Look, he wants to stop Manta same as we do.
And just for the record,
the only reason we made it this far is because of him.
I saw the Lost Kingdom.
Mom, I don't know enough about this.
Is that even possible?
All anyone knows for sure is there once was a seventh kingdom
and then one day, just before the fall,
every record of it was stricken from the chronicles.
How do you know what you saw was the Lost Kingdom?
No one even knows what it was called anymore.
It's called Necrus.
And I didn't just see it.
I knew it.
It's almost like I was... remembering it.
Flashes of someone else's memories.
During King Atlan's time,
there were seven united kingdoms of Atlantis.
And the Black City was a curse upon them all.
By exploiting orichalcum,
Necrus rapidly became a superpower unlike any other.
But it came at a terrible price.
Poisoning the land, the sea,
even the mind of the tyrant who ruled Necrus.
Atlan's own brother, Kordax.
- Atlan pleaded with him
to stop using it before the world
- was irrevocably damaged.
However, Kordax resented Atlan,
thinking his own brother was trying to steal his power.
So, he resorted to dark magic and crafted an instrument of evil.
That black trident.
He transformed his people and himself into monsters...
...to fight Atlantis.
So, the two brothers went to war.
But Atlan defeated Kordax
and imprisoned him and all of Necrus
with a spell cast with his own blood...
...to ensure that Kordax's dark power would never be found.
And that is why Necrus is stricken from the chronicles.
This evil was supposed to remain frozen for eternity.
But David Kane has found it.
And it's slowly possessing him.
But even with the ice cap melting,
Kordax still can't be freed.
Atlan used blood magic to seal Kordax in his prison.
Only Atlan himself could release him.
Manta doesn't need Atlan himself.
Manta needs Atlan's blood.
Blood magic isn't really magic, it's DNA.
The key to Kordax's prison is the royal bloodline itself.
That means he needs blood from either you, me or Arthur.
We're the end of the bloodline.
No, we're not.
