Quotes: Sealed Evil in a Can

Seals are meant to be broken.
Sage Ghido, Final Fantasy V

Moria. You fear to go into those mines. The Dwarves dug too greedily and too deep. You know what they awoke in the darkness of Khazad-dûm... shadow and flame.
Saruman, from the Fellowship of the Ring movie.

For seventeen long centuries have I remained in this blade, confined within these metal walls. During all my imprisonment you are the first I have seen who is worthy to bear me into battle. Come, take my hilt, and I will serve you in the manner of my kind, drawing the blood of your enemies, protecting you in the midst of the fight, bringing you safe home again. Now draw me from the scabbard and test the fitness of my balance. See how easily I swing, how my keen edge cleaves the air. A good choice, am I not?

Willingly you picked me up. Your first mistake. Willingly you drew me. Your second mistake. I do not allow my servants to make three mistakes, foolish mortal...
A Daemon Weapon from Slaves to Darkness, Warhammer 40,000

And so, once again, we find that the evil of the past seeps into the present like salad dressing through cheap waxed paper!

We try not think about the scariest one of them all. The gigantic, half dragon, half octopus, half humanoid Great Old One himself: Cthulhu! Waiting to return from his city beneath the sea!
Who day & night must slumber in R'lyeh?
Wave his tentacles, having nasty dreams
And who has the might, as master of R'lyeh
To drive humanity insane?
CTHULHU!!! Cthulhu!
CTHULHU!!! Cthulhu!

The ninth was strong and fought with might,
But lone Orannis was put from the light.
Broken in two and buried under hill,
Forever to lie there, wishing us ill.

"The Ancient Greeks foretold of a terrible container in which were housed all the evils of the world. How prophetic they were. All they got wrong was the name - they called it Pandoras Box, when of course they meant... Baldrick's trousers."
Edmund Blackadder, Blackadder the Third

Teysa: Hello, Pazapatru. How are you?
Pazapatru: Teysa. I am well and look forward to my freedom in precisely 2,281 years, nine months, eleven days, two hours, forty-four minutes, and... ten seconds. On that day I will destroy you all.
Teysa: I don't doubt you will, but I hope to be a ghost by then.
Pazapatru: That would be wise.
Magic: The Gathering: Guildpact

This place is a message... and part of a system of messages... pay attention to it!

Sending this message was important to us. We considered ourselves to be a powerful culture.

This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here.

What is here is dangerous and repulsive to us. This message is a warning about danger.

The danger is in a particular location... it increases toward a center... the center of danger is here... of a particular size and shape, and below us.

The danger is still present, in your time, as it was in ours.

The danger is to the body, and it can kill.
"This Place Is Not a Place of Honor," from Damn Interesting

"Ahh! After 10,000 years I'm free! It's time to conquer Earth!"
Rita Repulsa, Mighty Morphin' Power Rangers (opening theme)

You locked me into your stuffy little hyper-lock chamber and tossed me away in the depths like yesterday's trash! Do you have any idea what it's like to be locked up in a rotten egg for 6,000 years? It's BORING. Not to mention I've had a Charley horse since the Renaissance...
"The Adephagos disappeared into the void. Yeah well, guess that they didn't really say they destroyed that thing. They just went of and left this piece of crap remnant behind."
Yuri Lowell, Tales of Vesperia

"It is not a calling that can be made in an hour, or even in a day. There are many bars to be let down, sealed doors to be broken, locks to be opened for which the keys were thrown away. If we are to have help against Ardneh in time, I must begin now to call upon—the powers that are to help us."
Wood, The Empire of the East

"... they open doors to they know not what, they take down bars that were put up when they were wiser and more frightened."
Anita, also from The Empire of the East, on what Wood was doing.

"An Ancient Evil Awakens..."
Halo 4 trailer slogan

"Be bound here for eternity, Hunger stilled, Rage smothered, Desire dampened, Pride crushed. In the name of the Maker, so let it be."
Malcolm Hawke, Dragon Age II Legacy

Freddy: Hey, these things don't leak, do they?
After a terrible struggle they subdued Xerath, but they could not destroy his ascended form. Instead they trapped him within an enchanted sarcophagus and sealed him in an underground tomb. Eons passed, civilizations rose and fell, and Xerath's imprisonment was lost to memory. For centuries, Xerath's vast power tore away at the sarcophagus and weakened its spell. Finally, he willed forth a burst of magic that shattered his prison, but its core remained, containing Xerath and his power within its broken pieces.

"If an alien race possessed the technology to trap that thing and use Earth as their personal toilet, they did so for one reason...they couldn't kill it."
Lex Luthor, from Superman: Doomsday.

Chris: 'Listen, some stuff went down earlier and my crew has an opening for a hot mutant babe. It’d really help me out if you’d do me a solid and help me kill all the humans.' PS: Please enjoy the thought of Sir Ian McKellen referring to someone as a 'hot mutant babe.' You. Are. Welcome."
Matt: 'You just killed my best friend/lifelong rival and are clearly completely unpredictable in terms of whom you will kill and when. But, look, pobody’s nerfect.' PS: Enjoy the thought of Ian McKellen saying the phrase 'pobody’s nerfect.'
Chris Sims and Matt Wilson on X-Men 3: The Last Stand
