"There is certainly a maximum duration the drugs could last, yes, making a sufficient dosage for me has always been a bit of a problem for them." 

"Well, while you're waiting for that, if you have any questions for me, or there's anything you want, let me know."

Gelek opens his mouth, and then closes it again. What does he want? 

"I don't mean to be a poor guest." 

"I don't think you're being a poor guest. Believing that what they're experiencing isn't real is hardly the typical case for new arrivals, but this is a place for people like you, among others."

"Perhaps you had better tell me what this place is." 

"I've already told you the essentials. If you don't have specific questions or things you're confused about, I could give you the long version of the story."

"I was asking for the long version, yes." 

"There exist many, many separate worlds, which mostly keep to themselves, but under rare circumstances it is possible to travel between them. This one, we call the Eternal House. A seemingly endless series of rooms and hallways, sometimes caves and spaces which... pretend to be outdoors. It plays by its own rules. Things move around when you aren't looking at them, which makes it nearly impossible to navigate. Sometimes it obeys the usual physical principles most of us are used to, sometimes it would prefer not to. All these things make it very difficult for most intelligent life to survive. There are plenty of strange monstrosities, of course, either created by the house itself or somehow able to survive and reproduce within it."

"A long time ago, I found myself on the run from powerful enemies. I had nowhere to go, nowhere to hide. I thought I would die. Instead, I found a... distinctly extradimensional green door, and for lack of better options, went through. It was a one-way trip, as it always is, and I found myself in the house, as I described it to you. There wasn't anyone else here, whether because I was the first one to go through the door, or because none of the previous arrivals had survived, I don't know. In any case, despite the many dangers the house posed to mortals, there was nothing here that could challenge me, and I swiftly made myself at home."

Gelek has some level of awareness of other worlds - obviously the ogres (may they be devoured to the last child by their krumping idiot god) came from somewhere. 

"What does the house itself want?" 

"Ah, when I speak of the house wanting or preferring things, that's mostly a metaphor. It behaves in very complex and hard-to-predict ways that could be the result of a goal-driven intelligence, or merely a very complex mapping of random numbers to specific behavior. But if I were to interpret its behavior as purposeful, I would say that it wants to kill people in diverse and unsettling ways."

Really that could also describe most greenskins.

"Sometimes it feels like this is the principle motivation of the universe in general." 

"I don't know what the world you come from is like, but I strongly suspect you'd find the untamed house much more unsettling than you're used to."

"I hope I do not have to find out."

That would be a great excuse for this to degenerate back into the regular sort of night goblin induced hallucination. 

"Don't pass through any red doors, if you ever find one. That would take you out of my refuge, and into those parts of the Eternal House which I have not tamed and made habitable. Otherwise, you'll be fine."

"Got it." 

"At first, I thought I would be all alone here. But eventually, other people began to arrive through the green door. Their circumstances differed, but like me, they all had something to flee from, nowhere else to go, and nothing they'd especially want to return to. We later determined these are true of everyone who passes through that door, although not all arrivals to the refuge do. When my first guests arrived, I found myself glad to have company, pleased to be able to offer others the same second chance at life which I had enjoyed, and... unexpectedly well-suited to the role of a hostess. So I did my best to make this place hospitable to them, to shelter them from the dangers of the house, to which they were far more vulnerable than I. By exerting my power over a part of the house, I have been able to make it safer, more predictable, suitable for mortal life. Further improvements, like the translation effect, came later, and I continue to devise new ones."

"So, that's what this place is. My refuge. A home and sanctuary for all who find themselves here, carved by my power out of an enigmatic world hostile to intelligent life. Thousands of people have lived here, most of whom died here. Currently, I have four hundred twenty seven guests. Including yourself. I wish I could offer shelter to more, but that is—for now, at least—beyond my power."

"I do not think it is the case that I have nothing to return to. My people need me to be a steward and a rememberer of our fate." 

"What do you mean by that?"

"Once we were a great people, rulers of a vast realm, proud and free. All that has been devoured. Now, my people wander in ones and twos amongst the smallfolk, or are the slaves of the powers that be, either way filthy and starving and without knowledge of what they once were. I know of no other survivors of that age who still live." 

"And as a 'steward and rememberer', you do what, exactly?"

"Teach the young blood what I can of the old ways, when I can find them. Do my best to help them remember." 

"And this is something important to you? Something that you feel would compel you to return, if you could?"

"... Well. How could I not?" He doesn't sound enthusiastic about the idea. "They don't have anyone else to save them." 

... Was he saving them? 

She's going to let him work through this one on his own.

He'd rather not work through it at all, honestly.
