I have just added on to a summary already written by Brian:

The party ran into a rather large ice-golem that seemed to be immune to the pink light. Trust me — the first thing we did was have Merath zorch it, so she
stayed firmly in character (Wendy was absent this session). After that didn’t work, Merath cleverly cursed it so that its ice became rotted and brittle. Nathan found a giant bow in the chamber, but he wasn’t strong enough to draw it. Marath quickly blessed him to increase his strength. This allowed Nathan to shatter the golem with a couple of well-placed arrows, which was a good thing, because Jacob the Mighty (TM) was busy rolling 1’s. We learned an important lesson about ice golems, though — splitting an ice golem in two gets you two full-sized ice golems. So although there was some clever strategy and teamwork in evidence, we required the legendary cunning of Bastriel to get us out of this mess (Editor: This was in Brian’s original version).

After extricating ourselves from the Golem Menace, we wandered about the caverns, finding that they exhibited some odd physical properties. This was quickly dubbed the “Scooby-Doo Effect” as we found that when we left the central room via one passagway, we almost always returned to the central room via another passage.

Trail and error finally worked in our favor and we stumbled upon the a small “city” of humanoid moths (we had run into one such fellow a bit earlier in the evening). Bastriel straining the limits of his diplomatic skill instructed the Mothmen to “Take me to your leader,” and surprisingly enough they complied. Queen Mothra is her name, a blue-skinned beauty (much to Bastriel’s delight), and she informed the party, due in large part to Nathan’s gentle manuevering of the conversation, that all is not right in Moth-ville. Being heroes, the party looks like they are going to help, and there have been knowing glances exchanged about perhaps adding the mothmen to the Rose Kingdom’s faithful subjects.

The Rambling Bumblers (it is the Rambling Bumblers, isn’t it? Are we all agreed?) explored deeper into the Nefari-built ice caverns beneath the Red Keep. Coming to a huge fanged archway carved in the ice, Jacob the mighty sliced it apart with the Thorn Sword….and released an enormous Ice Worm. Unfortunately for the poor fauna of the ice cavern, Jacob’s skill at Giant Killing made short work of the beast. Unfortunately for the party, the carcass of the worm attracted the hungry attention of the cloud beast in the chasm, which poured up out of the chasm towards them. Eleazar quickly hurled some silver crescents and put up a ward to protect the party, and after some hemming and hawing, Merath of Yahar let loose with a full-power blast of the Rose Light to try and destroy the worm carcass, so that the cloud would lose interest. Merath forgot, apparently, that within the Rose Kingdom, the power of the light was nearly unlimited, and ended up vaporizing a 30-yard diameter sphere including the worm, the archway, a goodly chunk of the cliff, and the ice bridge that the party had come in on. Ooops. It did kill or drive off the cloud beast, though.
Buried in the ice they found a new PC, Nathan (played by Brian). Nathan had somehow came to be buried there after severely annoying a curse witch three years before, but he was fuzzy on the details. Seeing no other way out, he elected to follow them, although throughout the evening they gave him cause to wonder at the wisdom of that decision.
A bit of fancy work with the rope later, and the party was in the ice tunnel (twenty yards behind the original entrance); proceeding down the tunnel, lit by Merath. After a while, the tunnel came to be suffused with at first a blue, and then a blue-green glow. Eleazar came to be more and more aware of whispering in Nefari that apparently only he could hear. Spotting shadowy humanoid figures paralleling their line of march, Jacob slashed through the ice, revealing another tunnel, and the polished surface that was reflecting the party’s images. They moved over to the new tunnel, and a fair distance farther came to a big, deep cavern, reminiscent of the cavern of the Rose Light beneath the Rose Tower. In the center of the cavern was an icy platform, and there were 24 ice bridges from the platform to tunnels in the walls; below they could see another such platform, and another beneath that, which was as far as the golden light from the torch ensorcelled by Bastriel could carry. As soon as they stepped onto the bridge, the ambient blue-green glow went out, and Eleazar stopped hearing the whispering.
Merath refused to enter the cavern once she figured out that her precious pink light wouldn’t work there, so the others investigated the platform and discovered a Nefari spiral underneath the undisturbed snow. Unlike certain other PCs, they did not walk right across the hidden spiral, so no unexpected journeys to the Nefari lands for them. Yet.
They decided to explore the tunnels methodically, starting at the immediate left, and once they had gotten to it safely managed, with some difficulty, to persuade Merath to join them. Once in the corridor her light worked again, and she was much relieved.
Down the corridor they were attacked by a horde of tiger-sized Ice Weasels, who attempted to rip their flesh. They dispatched several, but there seemed to be no end to them, and eventually (once they rediscovered the fact that Merath’s pink light worked as a damage shield) they sent Merath out into the pack, and eventually the ravening weasels were reduced to so many cauterized gobbets of flesh. In order to prevent them from being used by spirits to make undead, Merath systematically vaporized the lot of them. In the weasel’s nest they discovered a fancy red stone box with gold trim, in which they found a Nefari magical charm (a ring linked to a bracelet) that they tucked away for future examination. There was a narrow tunnel leading out, but since they would have to slither through it, they elected to ignore it.
In the second corridor they found a barrier of differently colored ice, and when Jacob poked a hole in it, water poured out (presumably from the lake above); Merath used her hedge-wizardry to reseal the hole before the entire lake came in.
In the third corridor they discovered a temple with a Nefari altar of ice (shackles, blood-grooves and everything), which Eleazar ritually defiled–although the process of doing so knocked them all out. Upon recovering, they explored two of the three adjacent rooms, in one finding feathery vestments in iridescent blue and green, and in another many sharp knives and instruments of torture as well as a big black Book O’ Evil. Jacob attempted to set fire to the book, and burst into flames himself. Unable to put out the fire on his leafy form, he raced back to corridor two, cut another hole and doused himself. Merath followed, a little belatedly, and sealed up the hole before too much of the lake came in.
At that point, we broke for the evening.
