The Dark Crystal (1982)

Visible crew/equipment: Thin wires are visible, attached to the crystal bats as they fly off to watch Jen and Kira.

Narrator: Another world, another time, in the age of wonder. A thousand years ago, this land was green and good - until the Crystal cracked. For a single piece was lost; a shard of the Crystal. Then strife began, and two new races appeared: the cruel Skeksis, the gentle Mystics. Here in the castle of the Crystal, the Skeksis took control. Now the Skeksis gather in the sacred chamber, where the Crystal hangs above a shaft of air and fire. The Skeksis with their hard and twisted bodies, their harsh and twisted wills. For a thousand years they have ruled, but now there are only ten. A dying race, ruled by a dying emperor, imprisoned within themselves in a dying land. Today, once more, they gather at the Crystal as the first sun climbs to its peak. For this is the way of the Skeksis. As they ravaged the land, so too they learned to draw new life from the sun. Today, once more, they will replenish themselves, cheat death again, through the power of their source, their treasure, their fate - the Dark Crystal.

Trivia: The actors inside of the Skeksis had television monitors inside of their costumes, so that they could see where they were going.

Question: I believe I read somewhere that the worlds are connected by crystals and travel is possible. Is this true and where might I look for the answer?
