Standing before the group was a huge monolithic tower, that stretched well up into the sky. It appears to be made of some kind of metal, and had symbols on it that no one could even make a guess about.
"It must be a mile high," Sarah Jane said as she craned her neck to look up at the tower.
"If not higher," Garth said. "I don't think any of the human residents of this planet built this thing."
"The Ethicals?" Lynda asked.
"Possibly," Garth said. He turned to Olga. "You've been here longer than Lynda, Sarah, and myself. Did you know this was here?"
"Nyet. I'm just as surprised as you are," Olga replied.
Sam and Tesla made similar comments. No one had known of the existence of this tower.
I guess it is the Ethicals, Lynda thought.
Odd, that this thing should be at the exact point where I penetrated the mountains. Almost like it was all planned somehow, Garth thought. Given what has happened on Riverworld, that wouldn't surprise me one bit.
"Look!" Sarah Jane said as she pointed to the base of the door. What appeared to be a door of some kind was sliding back, revealing a way in. "Looks like we're being invited in."
"Question is do we accept the invitation?" Lynda asked.
"Why not?" Garth asked. "I think this is our party. Let's go." With that, Garth headed into the tower, with the others following behind.
