Accept to go with the spirit of the forest

The druid guides you to a glade, where a mysterious, big man with reindeer horns stares at you.

The druid steps away, and the mysterious man speaks with a deep voice that sounds like the wind and the rain.
"Traveler from distant lands, you seek passage. You are not hostile."

You explain your quest to him, and he says that he can give you his blessing, but he's not wise enough to know about your nature or any side effects that can happen to you.

The decision is yours.
