"Sit. I have supplies, and I'll be coming with you on your journey," she states, holding up a hand to forestall your objection as her other rummages around... in the air? A minute later she pulls out a pot, then some jerky, and then even some vegetables. "I have business with whoever wears the Amulet, and the roads are always safer when travelling together."

"Get some water from the lake and I'll get a fire going," she says, "We can introduce ourselves while this cooks, and plan the journey. Magical transport is out, not in these conditions."
