And so they would venture onward with some clarity of purpose, but still countless unanswered questions. Their course would take them deeper underground to the Withered Road, a subterranean highway that they discovered was used mainly by the scattered dark elf colonies that survived in the bleak passages of the deeper Fey Dark.
The party would ambush a patrol of drow caravaners a few days into their journey, and would then be chased deeper into the tunnels by the caravan guards, lying in wait themselves. It was only then, in their desperation, that they came to a great stone threshold that was sealed with massive masonry blocks, complete with a peculiar altar positioned deliberately in front of it. The gate was of ancient construction, and despite lacking any knowledge of the construct, Carric knew it to be their ticket out of there. He was quick to examine the altar and discern its purpose. Of all things, the magical book from Iarno spoke to him then, demanding that it be placed on the altar, with the inner voice seeming to compel Carric to action.
Wanting to hide this from the others for reasons he could not fathom, he laid the book down quickly while they were distracted by the fight with the perusing drow, and whether by his own volition or not, spoke the archaic words of power that willed the ancient gate to open. To everyone's astonishment, the gate began to glow with arcane light and then began disassembling itself. The party quickly rushed through the opening, and just as they were able to get across the threshold, the stones of the once-sealed portal began to crash back down to the ground, blocking the way with a rain of boulders and bringing down the ceiling above. Thus, the collapsed portal effectively prevented any pursuit, as well as any escape.
It was only after the dust had settled that they realized something terrible. Nizèl had been with them until the moment before the gate opened, but in the panic that ensued following the sudden change, none had taken note of the dragonborn's whereabouts. He was now nowhere to be seen, and they didn't have a clue if he had been following close behind and had been crushed, or if he had been further back from the others and had been stranded.
Either option seemed to spell death for their companion, though, and that realization was clear on every one of the faces staring back in disbelief. Nizèl had been the heart of the group. Not necessarily the one leading them into danger, but always being there in a supporting role, eager to step in and help at a moment's notice. His sudden absence hit the group like a punch to the gut, as unexpected as it was painful. That curious dragonborn that had insisted on playing games every night was now gone.
His presence would be sorely missed, but though it was painful, they had to move on. They were still in a desperate situation, and if they stopped now to grieve, there was a very real chance they would lose all hope themselves. Battered and beaten, the party made their way into the dark.
