Lance:
Lance chuckles. "Well, to be fair it's not every day that you have some grey skinned alien try to gut you for no apparent reason, so today is just sightseeing. Tomorrow is to be the real test. So Ballad, if you'd care to join us, I'd be overjoyed. Trent, if your duties allow, I'm sure your guidance would be welcome as well."
"My duties allow, m'lord."
Flora heads off down the tunnel.
Various other tunnels are passed, but the group of four moves in pretty much a straight line... until they reach a great, dark, metal-bound door.
From a pocket, Flora produces a key. "All of us in my generation were given our own key to this door," she tells Lance. "I don't have a spare... I'll see about getting you one..."
She unlocks the door. Opens it... and extinguishes the lantern she carries. Trent extinguishes his, as well.
The glow within this chamber is from the Pattern itself. When eyes adjust, you see it in the center of the room. It appears as a shining, shimmering mass of curved lines, inscribed into the stone floor, lines that fool the eye as it tries to trace them.

"To a Amberite non-royal, the lines are almost blinding," says Flora. Indeed, Trent is shielding his eyes. "To anyone not of Amber, they are not only bright, but hypnotic, as well. This room is not for casual visitors."
The Pattern begins in the far corner. "From there," says Flora, pointing, "the walker places one foot down carefully after the other, until-- after expending great physical, and emotional energy-- the Pattern’s center is reached. Upon reaching the center, the walker, by an act of will, can go, instantly, to any desired location-- upstairs, to the castle, or to the docks, or to anywhere on Earth, or to any of the Golden Circle kingdoms, or to any other Shadow-- anywhere. But only those whose veins bear the blood of Amber may walk the Pattern and live."
"After completing the Pattern for the first time," she sighs, "one may be taught to walk-- or ride-- between Shadows on one's own..."
