While Leargath is busy killing the last Despana guard upstairs, the others slowly make their way deeper into the dark passage. Phaedra, who is scouting ahead, catches a glimpse of a monster with leathery skin and red eyes. She is just about to warn the others when a scream of pain shatters the silence. Someone else is chanting, his voice rising and falling with the spell. Lilith quickly gathers her siblings in a close circle and uses a couple of spells to strengthen their party. Then the siblings follow their scout, chains softly moving against their bodies like a metal curtain.

In the distance, a purple glow lifts the darkness and a smell of decay is heavy in the air. When they turn the corner, they see a glowing summoning circle. In the middle, someone is thrashing on an altar, clearly in pain, while an arcane drow is pulling energy from his victim. Smears of blood surround the frightful scene.

Our DM used this drawing of dark cells (by Alex J. Moore) to visualize the dungeon.

The Xaniqos wizard summons an elemental to help them, but almost loses his concentration when a claw reaches for him from the dark. Almost. 😉 The earth elemental attacks the mage in the starred circle. The drow nimbly evades, chanting:

By the eight names of Lolth, I invoke thee.
By the eight dooms of the spider queen, I summon thee.
Fill my empty vessel with your profane might, your limitless power, and your inexhaustible wisdom.

With those final words, the mage draws upon the essence of a demon. His appearance changes. His body grows feathers, his head becomes a beak and he develops half wings. He turns towards the elemental and purple light shoots from his arms. The sonic force blasts right through the elemental, dealing much damage.

Calling out to the Spider Queen, Lilith creates a shimmering, magical field around her sister, brothers and herself. In the distance, they hear heavy chains rattling. Somewhere near more gates are opening!

Jharrath finds himself face to face with another demon. The tanar’ri is bent, horned, with a big mouth and claws. Acid gelly coats its slimy skin and half of its head is filled with teeth. They have found the source of the horrid smell: a babau!

Phaedra steps forward from under the portcullis and attacks the babau with her spiked weapon. She hits the demon, but the chain gets stuck in the skin. It sizzles but stays whole. She is aided by her fighter brother, who attacks the beast from the other side, but the two-handed sword attack does less damage than Alvra expected. Back in the corridor, the Xaniqos wizard casts a spell on the tanar’ri and the creature is sent back to its plane, growling, hissing and seething with rage.

There is no shortage of opponents though: two vrocks step into view near the circle, most likely as a result of the opened cages. The birdlike demons attack the elemental, but it defends itself well.

When Phaedra moves forward, she notices a device with multiple handles to the side on her left. A second babau, which is -she presumes- responsible for freeing the vrocks, is standing near it. The scout takes out her spiked chain and attacks one of the vrocks. Focusing divine power like a ray of the sun, Lilith also walks towards the circle, projecting a blast of searing light from her open palm that slams straight into the other vrock.

From the corner of her eyes, Phaedra sees the tanar’ri pull a lever, and with a loud clang the portcullis which they just passed, comes down. Alvra dives forward to be in the same corridor as his mistress, but Jharrath is trapped behind the iron gate! Quickly he casts a spell, and five more duplicate Jharrath’s appear.
