L_G, thank you.

Cooba entered the factory. The hallway behind main door seems to be ended with pair of stairs. But when he walked near it, he saw that one of them are locked by a solid metal grate. Then, Tangert pushed a brick nearby, and grate opened.
Ghost didn't want anyone of technicians to go down. He went there only with Cooba. The stairs were long, but they finally ended. It was very hot. Like in a factory or something like that.
Tangert pushed door that were at end of stairs. They opened. Cooba and ghost come through them, and they closed. Cooba looked back and he saw no door behind him, only the same concrete wall with the same bricks. (NOTE1 : Risp and Tangert has their own stairs to Factory Room) Then, Tangert come to door with label:

PYLON ROOM
Authorized Personnel Only

"Stay there" - says Tangert, showed him a corner of room. Cooba walked there. Tangert pushed a lever nearby door, and a comp voice said: "Authorization needed to enter Pylon chamber." Then, the laser beam blast from ceiling and hitted the eye-like shaped spot where Tangert is standing. Because of his transparency, beam went across him. Laser hitted the center of eye and started to detecting something...

"Authorization confirmed."

Door opened. Cooba was shocked 'coz of snareness of guy that built this security system... Tangert said to him: "Don't enter. I have to talk with master", and come across the corridoor leading to 'Pylon Room'.
Cooba waited for Tangert. Waited. Waited. Sleeped.
Sound of door opening awaked battle mage from dream. He looked at Tangert, but there was no Tangert. Instead, there was a tall man in a red shirt, black pants, grey with red stripes cape, black hat, and with blinking crystal in hand. Cooba thought: "Well, this should be this 'master' that this ghost was speaking about".
Rspss - because it was he - said to Cooba: "Well, you should be this bad guy that Tangent was speaking about. Hewwo. My name is Risp. What's your name?"
"Eww... Cooba. Call me Cooba."
"OK. Well, Cooba, Tangent said that you've defeated some guardians of this temple, while they were on medium-high alert. YaY. It is true?"
"Of course" - said Cooba. "You don't believe your own troop?"
"Oh..."
"Anyway. Are you the one that built this complex?"
"I wasn't alone. Some guys..."
"OK, thank you. Well, I must say, that it has very well security grid. Nice place to hide."
"Errm, we have something STRONGER to hide *cough*" - said Rspss, touching the label that say "Pylon Room(...)" with his finger.
"Oh." - told mage. "And what is this Pylon?"
"It's a machine. It protects the current dimension against being invaded. All things that tries enter it while Pylon works, are sent back."
To be continued...
