I'm happy that you found something pleasant here, but, you must carry on. Even baring the idea that the Lady herself will be displeased by the choice to sit down and never move, I'll have to keep charging you, and you'll run out of resources, and if you don't leave at that point I'll be forced to take steps. So, one way or another you'll be moving on in your quest."
"It is an Oasis, We are servants of the Lady and we stay at those points between.. Arbitrary points in this place. Those of us who serve here do so because we want to see the questers succeed. Here is a bit of a secret for you. The Lady wants you to succeed too. There is a reward beyond my ability to describe, nor my permission to disclose, but.. Reaching the end is worth it." She cleans one of reds many many glasses, "There will be many challenges as well, but hopefully you all think well enough of me that I may return."
A sign reading 'Exit' in each of your primary languages appears above the door. "Go now, or choose to stay and eat up your resources and risk boring her.. I wish you well."
