John Carter: [as the trio arrive the Gates of Iss which looks like a giant umbrella-like rock formation] Professor. Dejah Thoris: Impossible! I've never seen this kind of structure before. John Carter: I wanna get a better look. [suddenly Carter grabs Dejah and leaps to the top of the rock formation] Dejah Thoris: Carter, your feet! [the medallion Carter carries lights up blue and as they look down they notice the center of the rock begins to lower and a set of stairs emerges, the stairs lead into a cave where the walls form blue webbed material] Dejah Thoris: This is not the work of Gods. These are machines. Your medallion. John Carter: [Carter gives her the medallion and Dejah places it on the glowing spider carving on the cave ground] The spider. Dejah Thoris: [nine blue glowing rays suddenly appear out of the spider symbol] Nine. Nine rays. Nine! The Ninth Ray is real! It can be harnessed, do you see? This entire structure runs on Ninth Ray isolates. The Iss is such power, and somehow Zodanga has it. The Therns, they must be real. And you, you are John Carter of Earth? John Carter: Yes, ma'am. Dejah Thoris: And the ships that sail on the sea, you've seen them? [Carter nods his head] Dejah Thoris: That must be a beautiful sight. John Carter: It truly is. [as Carter steps on the blue ray light suddenly the set of symbols connects and the solar system appears on the ground] Dejah Thoris: It's our solar system! John Carter: [Carter steps on the symbol of Earth and a set of symbols connects the planet to Barsoom] What's it saying? Dejah Thoris: I'm not sure. John Carter: Okay. What do you think it says? Dejah Thoris: It appears to be... a kind of technical diagram. Here is Barsoom, there is Jasoom. This bit here, it's like our symbol for a transcription. A copy, sent along these lines here, between the worlds. Like... John Carter: A telegram. You're saying I was telegraphed here. I'm a copy of myself. Dejah Thoris: Possibly. Making these words here, the command for travel. Dejah Thoris: [referring to the symbols they've just discovered] I don't like guessing. I need more information, I need charts, codices. [Carter looks at Dejah with suspicion] John Carter: Right. And where might we find those?
