He takes you back to Hell

You are not given any time to ponder what Mar'aath means when he called you a "trophy". In one swift movement, he picks you up and heaves you on his shoulder before grabbing his recent conquest and holding her under his arm. With his two spoils secured, he takes a few massive steps back to the summoning circle. You can only watch as the wind kicks up in the laboratory again. Slowly the cold stone of the room begins fading away, and a smell of sulfur begins to fill your nostrils. The summoning circle begins glowing a bright red. The light continues to grow exponentially and several arcs of lightning jump between the runes. Eventually when the light is bright enough to nearly blind you, it all disappears in an instant. You open your eyes and are surprised to see a raw stone floor and the summoning circle completely gone, instead replaced with a corona of scorch marks radiating out from where the demon now stands. You look up and realize you are now in a large room. The only light coming in is from rows of tall, thin windows with frosted panes, through which emanates an eerie orange-red glow.

Mar'aath drops his two prizes to the floor. You barely catch your fall, landing on your hands and feet, while your former master simply lands on her side in a heap, apparently too horny and distracted to care about her current situation. You look up at the demon and absentmindedly ask, "Where are we...?"

He laughs deeply. "A place few mortals ever experience. My home, and now yours as well." As you are taking a moment to ponder what exactly that means he points a finger at you and his fingertip begins to glow. You feel a searing heat on the base of your neck for but a brief moment before he turns to his other captive and casts the same spell on her. With her back to you, you see the insignia being etched between her shoulders. It glows brightly for but a moment before fading completely away. It is nothing like any spell seal you have ever seen before. You look back up to the demon with a questioning look. "This protects you from other residents of Hell. As long as you are marked they cannot harm you." You sigh a breath of relief, but in the back of your mind you recognize that he specifically did not mention what he would do to you. "Come now, follow me. It is time for you to take your place in this world."

Without much other choice, you follow your new demonic master to the massive double doors on the other side of the room.
