"You chose well," Janek laughs, "for there is no friendlier place in all of Barovia. Or, at least, no place freer with its wine." A peal of hearty Vistani laughter follows this.
When you mention an alliance against the Lord of the Land, the celebration becomes muted and Janek looks surprised... but not too surprised. "Ah, you are bold to be making that talk out here in the open. We will protect enemies of the Devil all we can, but this is very much his domain." Another Vistana refills your wine as Janek settles in to tell more. "We have been working against the Devil who rules these lands for many generations. We do all we can for the people who come here as liberators, so I see no reason why we cannot do the same for you. Just know that there were people who stood where you stand now, and they paid for their optimism with their lives and more. It is not an easy road."
Another Vistana nearby pipes up. "He's talking about the wizard. An old wizard came here a year ago, stirred the peasants into revolt. When the peasant army marched on the castle and got one look at the Devil's terrible pallor, half of them turned and fled. The rest were taken into the castle and never seen again."
Nothing makes a sound except the popping of the fire. "I saw the battle with my own eyes, and so did Janek and a few others. Thunder shook the mountainside; the Pillarstone of Castle Ravenloft trembled, and we thought it might fall. Still the wizard was unharmed, kept safe by strange magics. The Devil called lightning to strike him, but still he stood. Finally, the Devil threw himself upon the wizard in all his bestial rage. The two fell from the spires of Ravenloft to the bottom of the mountain. No one ever heard of the wizard after that, but we all saw his tattered cloak on the river."
Janek clears his throat to get the conversation back on track. "Ahem, yes, many have fallen before you, but we will offer what aid we can. And we will not force you to move against the Enemy. If you do however, you would be a savior to all of us and your dear friend, whom we can only hope escaped these lands or is trying to."
