Chewbacca was down by the engines when Han found him.
"It's nice to be able to see again, huh?" Han motioned to the lights while talking to Chewie.
Chewie grunted as he had the hyperdrive wide open with many large chunks of engine parts all over the large engine room. The main hyperdrive engine took up almost the entire room from wall to wall.
"Yes, I know. Thanks for fixing the air," Han replied to him. "Look what almost killed me under the main deck." Han held up the spiny droid by its legs and twisted it oddly before throwing it onto the floor towards Chewbacca.
"What do think that thing is?" Han asked.
Chewie picked it up and carefully rotated it. He took a long knife-like tool and poked at the back of the droid. Instantly the little back opened up to reveal a compartment. Chewie took another tool and pulled out a long cable that had a little folded dish antennae at the end of it. Han came over and knelt beside him looking carefully at what he had found.
"That's a transmitter alright. It looks Imperial to me. Great," Han said as he sat back against the hull.
"Yaahrr grrrr aaagh aagh" Chewie spoke as examined the small antennae closely.
"Homing beacon, eh? I guess the princess was right about that after all," Han said to him. Chewie grunted back in reply.
"Well- you don't have to take her side every time. She called you a walking carpet, remember?"
Chewie laughed a few snorts and moved a couple of pieces of the hyperdrive to one side to get closer to the rear of the gargantuan engine. There were access panels dimly lit, pipes that came out and just stopped, some were even cracked. Steam drifted along the floor along its massive metal edges. Han walked over to some valves and twisted them closed and the steam stopped. Chewie grunted quickly, he was watching Han intently as he walked around. Han slowly strolled back and turned the valves open again.
"Happy?" Han said.
"Yaaarrrrgh", answered Chewie.
"Man, you gotta relax", he said as he made his way out of the engine room.
Han only went a few feet when a tremendously loud bang shook the ship. He stopped in his tracks and went down on one knee. Then there was another one and all of the lights flickered. Chewie came running up next to him and both of them headed towards the bridge.
By the time they got there several more slams shook the ship from all directions. They ran into the cockpit and were astonished at what was before them in the windows. There were at least three small ships a short distance in front of them with long cables stretching out of their sterns towards the Falcon. There were two more smaller ships zipping around, fighter escorts.
The closest ship with cables fired two more that rocketed towards them and hit the ship hard. Instantly they attached somewhere below and the Falcon shook again as the cables pulled taut. Han jumped into his captain's chair and powered up the weapons controls. With a few clicks and switches the small automated guns located on the bottom of the hull let loose a barrage of laser blasts at the ships. Immediately the ships moved back, the lasers splashing against their shields in brilliant bursts of light.
The cables kept stretching further and further as the ships moved away. It was amazing how long they were. After a few moments they began to get tight and then started to pull. The Millennium Falcon lurched forward under the strain, throwing Han and Chewie back in their seats. Han repeatedly tried to manually aim for the cables. He landed a few blasts that only bounced off. The tow ships fired up their engines and rapidly picked up speed.
"The cables are magnetically shielded. Probably how they are attached to the hull. Looks like we're in for a ride", he said to Chewbacca.
Chewie did not respond, but kept looking out the window at the ships, trying to figure out who they were, and what they wanted.
