Wait 10 minutes or so. If something obviously hostile shows up, press yes. If nothing does, the screen is likely referring to us so select no.
Kill time by getting Jessie to monologue about the sword and it's significance.
You decide to leave the screen for now, and instead ask JESSE about the DIVINE SWORD.
JESSE exposits that the sword once belonged to his ANCIENT ANCESTORS, who were favored by the GOD OF ILLUMINATION.
According to tales from his childhood the sword was created during a time when VEGA, PRINCE OF DARKNESS took the land for his own. The Prince was eventually beaten back when the warrior ADALANX THE SPARKLY, crusader of Light and JESSE'S great-great-great-great grandfather, slew his AVATAR in combat.
He says that the sword, crafted with the power of a God, should be able to cut through anything touched by the foul hand of darkness.

After climbing through the destroyed obstruction, you walk for several minutes down another dull featureless hallway, who's only noteworthy is its exceptional dull featurelessness.
After travelling several dozens of meters, the scant light begins to dim even further.
You see what you think is a human ahead, but it is hard to see.
