"For the first few hours after you dumped me here, I lay barely conscious in the Dagobah mud. The first thing I truly remember was the swarm of nudj around me - the tree lizards you used as bait for the dragonsnake. But they weren't interested in eating me - no, they were drawn to the Force within me.
"The nudj are apparently a species of Force-sensitive lizards. They survive this predatory environment by linking their minds together through the Force to form a giant consciousness that senses far beyond what any single nudj can. Their combined perceptive powers allow them to create a map that weaves visual, auditory, olfactory, thermal, and magnetic information into a unified tapestry that maps out hundreds of square kilometers of the planet's surface at once. In this way, they can all perceive predatory threats and move themselves to safety before the predator even knows any one nudj is there.
"Unless, of course, that predator is also Force-sensitive. That's where your beloved dragonsnake comes in: it detects the use of the Force and hones in on any concentration of Force energies it can find. However, sometimes it can't physically reach the nudj it has sensed through the Force. In that case, it reflexively uses its own type of Force power to disrupt the nudj communications network. This power seems to be dark sided in origin, as it floods the minds of all active Force users around it with horrifying, unspeakable sensations.
"Just like what you used to torture my mind into submission.
"And they work, too. When assaulted with the dragonsnake's Force blasts, the nudj either drop from the trees or freeze utterly, making them easy prey for the dragonsnake's ravenous jaws. It scoops up as many nudj as it needs to satisfy its appetite, then it dips itself back beneath the black surface of the water, swimming away to places unknown.
"Fortunately for me, the nudj crowded around me to provide a shield against the dragonsnake's Force manipulations. It was as if they could sense how vulnerable I was, and they took it upon themselves to protect me. They cloaked me under their web of Force sensations, and the first time a dragonsnake reared its ugly head toward me, over a hundred of them rolled me away bodily from the banks of the bog. Several of them sacrificed their lives to ensure I made it beyond the reach of the dragonsnake's neck, barely able to help them as I was.
"However, they could not keep me protected forever; they still had to forage for insects and moss to sustain themselves. Though they attempted to keep a rotating guard duty over me, as I regained consciousness, then strength - from the grubs and roots they pushed my way - I insisted through the Force that they go about their usual business. They had done quite a service for me, but I reasoned that their continuing presence near such a strong Force source would only make them more vulnerable to the ravages of a deeply hungered dragonsnake.
"And soon enough, my fears proved true. After regaining my strength, I wandered a bit too closely to the banks of the bog, my compliment of nudj bodyguards nearly swarming over me. Without warning, waves of horrific images flew through my mind, sending me to my knees and making me cry out with pain. The poor nudj, torn among their desire to flee, their perceived duty to protect me, and the assaultive nature of the images roiling through their collective mind, were frozen in terror and dread. I could do nothing but writhe with my compatriots, ready for the dragonsnake's strike to end us all.
"But obviously, that end never came. A behemoth sac of protoplasm called a swamp slug rose up behind the dragonsnake and devoured it whole. As the swamp slug approached, I felt the disturbing images bounce off my mind - they didn't leave me entriely, but it felt as if they were redirected from me back toward the dragonsnake. The swamp slug also detects Force usage, though it seems as attuned to the use of dark side Force powers as the dragonsnake is to the light side of the Force.
"The dragonsnake collapsed under the psychic weight of the gruesome images playing doubly back into its mind, leaving it defenseless as it slid into the swamp slug's maw. At that moment, I understood how to defeat those that would use such imagery to subjugate others. Instead of fighting it, trying to suppress it, to make it go away, I learned to embrace it - then shunt it directly back to its source.
"I realized that the use of any Force power opens the mind to any other Force user, to a certain degree. A skillful Force user with untoward desires - like you, Dooku - can widen that opening and break his or her way into the psyche of the person who first used the Force. He or she can read the first Force user's mind to the degree that it was opened to the Force in the first place, and then he or she can use that opening to take control of that mind.
"The problem is that the opening then goes both ways. The minds of both the original Force user and the one seeking to enter the original user's mind must be open for the Force to pass through. And if that original user can acknowledge - embrace - those Force currents that the other user is employing to place the disturbing images, the original user can then redirect those Force currents back through the mental opening of the other user.
"And so I quickly learned how to redirect the images the dragonsnake tried to feed into my mind through the Force right back at it. To be sure, it was difficult the first few times, and I barely walked away from one particularly ravenous dragonsnake's Force horrors. But over time, it became almost automatic, like reflexively throwing a lightsaber block or parry. And soon enough, the dragonsnakes all knew not to go near me, lest the horrors they sought to visit on the minds of their prey be returned back to them doubly, trebly, or worse!
"I tried to teach the nudj my defensive trick, to implant it into their collective consciousness. But they didn't seem to grasp it instinctively, and I couldn't use my words or the Force to drive it home to them. Nevertheless, I keep trying, as a way to pay them back for the care they showed me when I was defenseless.
"And I expand my teaching efforts to all the creatures of Dagobah, so that they may not live in fear of the ravages of the dragonsnake. The sleen - long, ground-dwelling lizards - the spotlight sloth, the gnarltrees in which I perched during our battle, the knobby white spiders that issue forth from the gnarltree roots when they wish to reproduce, and the bat-like bogwings that fly above and below the arboreal canopy - all have received my tutelage in how to defeat the dragonsnake, to varying degrees of success. But they all now know the Living Force's ability to turn back the darkness of the dragonsnake's Force powers, keeping them alive as the dragonsnakes starve. True, this means the dragonsnakes may grow hungry and mean before dying out utterly, but that is the price one must pay to eradicate their evil from this planet.
"But Dooku, as I have told you this, I have seen into the deep recesses of your mind. I see your fates, the possible paths your life will take, the threads of destiny that you have tried to hide from me so assiduously. And this is the moment, the choice that will decide your place in posterity. Will you be remembered as a valiant hero who turned from his sinister ways in his last days, or as a long-lived traitor, fated to betray and destroy all that he once held dear?"
