You walk through the door and into a hallway carved into the earth, a space not dissimilar to a mineshaft tunnel.
From behind you the door closes but not before you hear the door give you some parting words.
“Gallantry will not save you in this place, Seer. The challenge behind was but child’s play to what you will face ahead. You will not survive if you become blunted to the reality before you. Be careful or perish.”
You heed the door’s words to the best of your ability. You walk on.
