On the trail of the heroes...

The descent into the underdark was very much like any tunnel. The damp air, the earthy smell, the occasional stalagmites and moss covered walls. Aside from the glowing worms, there seemed no mysteries, and after Fylikiel explained that these worms were simply feeding on the spores of Magivore plants, a coral like plant that feeds off magic, and doing so changed them strangely. Nothing scary so far, so the heroes were chatting silently, Auburn inquiring on Liw's past, or their purpose down there... when Acane silenced them. She'd heard the echoes of something Liw had just said, but distorded, repeated, whispered, up ahead. Quiet and alert, then went forward into a tunnel formations, branching and folding back on the main passage... Auburn and Aishar went first into the center tunnel, to fall face to face with a mound of bloated flesh, covered with horrible mouths and eyes. While at the same time, from the right, a tentacular floating brain with a large beak came from a niche in the ceiling and fell down on Liw. Aishar lashed the beast closer with his lightning whip, only to realize with dismay that the senseless gibbering escaping from the creatures countless mouths were not only annoying. They were sinking painfully into his brain, and even seemed to warp the very ground around it, making him sway and move with difficulties. That is when the mouths on his own body appeared and bit at himself. If that was not horrifying enough, another such aberration came from the left tunnel behind them, causing the same pains to all the others. Worst still, the Grell then fell on Liw, grabbed him, bit him, and the warlock's body went senseless as the grell starting floating back, dragging a stunned Liw along. Only the rays of frost of Fylikiel kept the monster from floating away with Liw as the warlock struggled to stay conscious. Aishar and Auburn were stuck between the two gibbering mouther, and everything seemed lost, but they held it together and with with extreme luck, just barely came out of it, all alive.
Their trip into the underdark was not so amusing after that, and some even thought of going back, finding a way out. But Acane reminded them of their purpose here... So they went forward, found a hidden cave well out of sight from the tunnel, and tried to get some rest. Again, they were discussing, when again came in a hurry. She had peeked out to stand watch, and seen the large body of a large snakelike underground predator she called a Grick. It lay there in spasms. Liw examined it and came to the conclusion that it was dying. Auburn found tiny nasty looking bolts. They all turned and looked at each others, shocked. They understood what it meant: drows. That damn neared convinced them to turn back, but somehow they steeled their nerves, slept with a tight watch, and woke up alive. The following day, they started again down the caves, and their conversation was more quiet this time. As their discussion swerved toward the drows again, they were interrupted by an unseen woman clearing her throat. Turning around, they were struck silent as before them stood a gorgeous, yet terrifying drow female in platemail. Their fear were soon forgotten though, as she presented herself Nayism'Na, and said she required their help, as they had a common enemy: an undead rising mad eladrin had moved into long forgotten buried ruins. She explained she'd do quick work of him, as his presence was a nuisance, but the drows couldn't reach the ruins. She remained a little as to why, but said they would understand. Liw was even so bold after their agreement as to offer his help in the future, if the drows required help at the surface. She smiled and freely admitted to be of Bregan D'Aerthe, a name the two pirates had heard whispered before. Nayism'Na promised they would discuss it further, given they survived the tunnels. She drew them a map, and the was gone.
So they went on in the depths of the world, coming across some caves halfway to their destination according to the map. Curious, they moved in, only to disturb the meal of two carrion crawlers. As they fought, their group separated in two, they experienced the nasty paralyzing poison these beasts were notorious for. First, Acane, then Liw again. Then a third crawler came from a hidden passage. Then as one retreated back in fear, Otyughs jumped up from their nests under refuse piles, at the back of the cave, and attacked them from behind. After much being thrown around, they defeated the dungeons beasts, but not without lasting pains, for Auburn and Aishar contracted the nasty filth fever.They picked up remains from past adventurers, while Liw gathered a heaping pile of crawler eggs, tiny compared to the mature ones, and hid it in his Handy Haversack.
And on they were again, soon to come to what the drow had labeled as the Plaguecaves. They soon understood what it meant, as Liw and Fylikiel felt the distinct arcanic taint of the spellplague. The bright light at the end of their tunnel turned out to be what seemed to be bright daylight. And it was, for when they exited, they seemed to be outside. The cave was not a cave, but a immense pocket of raw spellplague. And much like the plaguelands of the surface, this place was "scarred" in ways that defied understanding. They were standing at the edge of a cliff, lost in clouds, with the blue sky and sunlight. The edge was dripping bits of earth and rocks upward into the air, carried by a cool wild breeze...
