As Velaine stepped through the portal leaving that room that belonged to the Seekers, she'd find herself transported to a new room, made of the same exact stone, with ancient runes carved into the walls. But upon her arrival, the tired spark upon her soul was recognized by the building she was in. And so, in a deep, rumbling voice around her, the structure spoke.
"Welcome Velaine, the third of your kind. You have proven yourself worthy by one of the great Eternals. You have been entrusted with this place as a gift for your service. It was first given to those who came first, that some call The Shay. It was later claimed and subsequently lost by those called the Seekers. It is now yours, and yours alone. Within this place, you will find that the world outside knows not of your presence here. None may enter here, none may spy into here, and none may be heard in here. Those who have toyed with your life know not of this place."
And so, the structure, which was merely a room, revealed itself to Velaine. Velaine would find that while the room was bare, it had the capacity to grow. She would know that it was deep underground in Yaralon. And she could make it grow with her own will. She could shape this structure into that which she desired. And should she wish to leave, the door would present itself to her, returning her to Yaralon.
