Storm on the Horizon

Lord Bowell violently jerks upwards as the potion burns its way down his throat. He mumbles something as his face turns a deep, unnatural purple. The veins along his neck bulge, and blacken, beneath his skin. He gasps for air, trying to fight off the effects, but then his body betrays him and he collapses once more into the mud, body trembling and hands clawing at the muddy ground.

Soon, spit and blood bubbles form his mouth. His muscles tighten, and then he lies still in the mud, his chest barely rising as he struggles to breathe.

You drag Hans' limp body through the rain and into the entrance hall, and lay him down across the stone floor.

The halls of the castle are eerily quiet. You find the remains of half-eaten meals, overturned chairs, and abandoned cloaks. The guards, and the servants, must have left in a hurry once Lord Bowell became more and more erratic. When you reach the lord's chamber, you find Lady Halia lying in bed, soaked in her own sweat. It is cold and raining outside, but the lady is feverish with the same curse that afflicted her husband. Her wet tunic clings to her skin, her hair is disheveled, and all she does is mumble Hans's name as she twists from side to side.

Just as you wonder whatever happened to the children, you hear a faint noise from the adjacent room. A muffled sob, followed by a hurried 'shhh!". The kids have barricaded themselves in their room, and bolted the door from the inside.

What do you do?
