[X] Search to the south - it's a lake, it's bound to have some of the things.
You shake your head. No, no, you have it all wrong! Get the work done first, then you can go play around! And it's not like you can't enjoy things while you look for the plants …. With that in mind, you turn to your left and walk to the edge of the cliff and look down. With the giant glowing tentacle-things, it's bright to your eyes, and the surface of the water is clearly visible hundreds of meters below you. So are the waterfalls that feed the lake - curious, how the sound is muted when you should be hearing a continuous, crashing roar - and your mouth twists in distaste. Those are running water, and their presence means the lake below is probably not going to be particularly pleasant for you, should something happen and you end up underwater. You'll simply have to make sure to avoid that particular occurrence. You begin your descent, drifting gently down toward the lake's surface, keeping an eye on the pillars and columns that rise up from the lake. To your left, against the cavern wall, are a series of dimly-glowing mage-lights that would normally be illuminating a stairway. You slow to a halt several meters above the water - the sound of the waterfalls is as it should be down here - and begin your exploration, sweeping back and forth between the stalks and columns.
One of the columns turns out to be more than it appears, with a stone platform and some steps leading down into the water marking a solidly-built double door made of some heavy, brass- or bronze-like metal. Probably, anyway - you're no metallurgist, after all. You decide to leave the tower alone for now, though, and continue your sweep. Oddly enough, you don't see any fish or other life in the water below you. Perhaps there's something poisoning the water? You find your first prize growing near a broken pipe, still pouring water into the lake, and carefully dig the plant out of the rocky soil and put it into your pack. Normally, you would simply put it with your other things, but the plant is magical, and - if Tolfdir's half-aware ramblings were accurate - might have some kind of direct connection to the plane itself. If that is true, severing that connection might affect the results the College would get from their tests. The first plant successfully gathered, you continue long the wall toward the stairs. You find another plant near a waterfall and dig it up as well, despite the minor burns from the water. Prize gathered, you dart back up the stairs. Perhaps a location that is a little drier will do, for now. You shake your hands and drift upward, following the stairs deeper into the cavern.
A pair of white-furred, three-eyed creatures laze among a small pile of bones - most are humanoid, though some are not - and you would leave them be, except that the drone and glow of another Nirnroot attracts your attention, hiding around more large pipes. Shrugging, you drop to the ground and walk forward, humming. Sure enough, the creatures hear you, and you grin at their frenzied hooting. The first one comes rushing toward you, loping on all fours, and you slip past it, grabbing one wrist - as thick as your own torso! - and hurling it over the edge. The second pauses and stares at you, head tilted, and you consider it, wondering if it's a trick of the light or if there's actual intelligence in those eyes … but then you hurl yourself forward and slam into the creature, shattering its rib cage and knocking it to its knees. It coughs and chokes as it tries to hoot, and you stare in fascination as its chest tries to knit itself back together before your eyes. You don't give it the chance, though, and rip its head off. Carefully, to avoid getting its blood on you. After a moment to let the thing's corpse settle, you rub your fingers in its neck and start to lick the blood, but something reacts badly and you have yourself a little coughing fit. And it didn't even taste all that good, either, too bitter. Once you get the taste out of your mouth, you head for your goal, the third Crimson Nirnroot. That finished, you keep following the cave wall, flying up to reach the next level. There's another waterfall you have to avoid, and you probably fly out farther than you need to, but it's not like you're in a rush right now.
You're greeted by a metal fence, the same kind of metal as the door below. You drift along the fence, admiring the workmanship of the metal, the stonecraft of the walls and supports, until you find a massive doorway, almost as big as the main entrance to the mansion back home. Wishing you hadn't thought about that - you're sure Remilia would have something to say about this place, maybe that it's tacky, or the wrong color, or …. You shake yourself and take a few minutes calm down. Then you turn around, ready to head back down to the lake, only to find yourself staring straight at one of the goblins from the ambush. It looks at you, cocks its head, then … turns around and carefully makes its way to the bridge leading back to the elevator. Your eyes narrow, then widen as you realize that they're blind. Their other senses must be sharp enough to let them move and fight effectively within a certain distance, but they aren't very powerful, or it would have heard or smelt you. A grin creeps across your face, and you drift forward silently, then grab the creature by the skull, your claws digging into its skull, and it writhes and hisses as you pierce its brain. You toss it over the edge and turn when you hear more hisses and snarls coming from your left, and you sneer at the quartet of creatures facing you. Armorless, wielding weapons of black chitin, barely clothed at all. Blind and helpless. And yet, they hurt Agito, and you're in the group as your rage rises. A crushing blow nearly explodes one's chest, another has its head pulverized. You lean down and grab the third by an ankle, slamming it back and forth against the rocky floor. By the third strike you're left holding only the ankle and a portion of the calf, and you use the bones as an impromptu weapon, driving the shattered leg through the skull of the last chittering creature. You float above the corpses for a minute, breathing steadily, just … waiting.
But nothing else happens or attacks, and you shake yourself. You swing around, heading for the only place where the reinforcements could have come from, and across another stream that flows into a waterfall you find a small camp. Several small tent-like structures, almost permanent and made from a rough black material similar to the jagged weapons and armor of the goblins but quite distinct all the same. You find chopped-off mushrooms in each tent, along with some putrid or rancid fish. Outside one of the tents, off to the side by the stream, you find a small bowl and a similarly-sized club; inside the bowl is a mixture of powder and a number of as-yet uncrushed materials, and on the ground are what seem to be fish remains, some sort of twisted root, and some vibrantly red shredded leaves. You scowl; if these goblins have been harvesting those plants, you're going to be very upset - especially since that would mean you won't be able to simply burn them all with Laevateinn! Of course, maybe they're cultivating them …. You sigh; things probably won't be that simple.
You frown as you descend once again to the lake. The goblins are obviously not responsible for building the structures you've found here - their own equipment and dwellings are far too primitive, the style too different, and a blind race wouldn't bother with the decoration on the stonework, the impressively-sculpted metalwork. And someone who went through the effort of building such impressive monuments probably wouldn't leave them open to the goblins, either. So what happened? You mull over the myriad possibilities as you drift over the lake, making sure you haven't missed anything, and you do find one more Crimson Nirnroot … but as it's very nearly underneath a waterfall, you're content to leave it. At least for now, and hopefully forever. Still, it's something to remember, and you keep its location in mind as you fly back up to the main level of the cavern. You fly over one of the waterfalls and settle on a huge outcropping, well away from the water below and offering a commanding view where it isn't blocked by one or another of the columns supporting the cavern ceiling. You check your pack - yep, still have three plants, all in good shape. A very profitable several hours, all things considered. You could probably do some exploring if you wanted to … maybe see what's through those doors you found? Or maybe you should just wait for Lutecia to contact you before you continue. You really should keep looking, but ….
What do you do?
