With politeness.

Your party goes to the hag’s door, and you politely knock.

The hag calls out “It’s open.”

You respond, “And it would be rude of us to enter without permission.”

She frowns, “Then come in, if ye mean me no harm.”

You enter and smile, revealing your fangs, surprising her a bit “Well spoken.”

“What do ye want with me?” She waves you to sit down at the table she has.

“I have come to offer fair trade.”

She looks at you cautiously. “What do ye seek, and what do ye offer?”

“I have a few things to offer, but I know not what you can offer me. I shall go first.”

You lay out a Claimant Crystal, the onyx, silver ore, bone dagger, vials of poison and 10 rations

Her eyes were immediately caught by the crystal, onyx and ore.

She looks at him “What is it ye seek and aim for?”

“I plan to claim a place of my own. A place of undeath and fiends. Those hunted by the forces that seek to claim to be Good.”

She sat back and thought for a bit.

Looking him over, she lets her eyes lose focus and then smiles in a horrible way as she refocuses them.
