She wastes no time dashing up to the door and throw it open, you follow after her and she shuts the door once both of you are through.
Behind the door is a passageway carved into the cliffs, overlooking the moonlit sea. It leads downwards to the stony shores below, where a lone hut sits. Making her way down to it, she notices how... unkept everything is. As if no one has ever step foot here for ages, the passageway appears to be weathered and overgrown with vegetation.
Unbeknownst to her, the door has vanished behind the both of you. You watch with curiosity as it shimmers out of existence, its finely-carved frames melting back into the stone.
The only way forward is the hut, a stone construct that seems to be grown and shaped out of the very stones underneath it.
The two of you stand before it, unsure whether to enter or not.
