Catacombs and dead ends

With the seraph following the map, you follow her through the catacombs beneath the church. Dark tunnels lit by torch sconces wind in multiple directions; without the map and the angel to read it, you would surely be lost.

After several tense minutes of what felt like wandering, the seraph stops. Looking around, you are at a dead end.

"This is it," she breathes.

"It is?" You don't quite see it.

Turning to you with determination in her eyes, the seraph says, "My true name will open the door that leads to the sealed chamber. The seraphim were too late in ancient times. When they hid the Purestone, Lilith put a barrier of pure darkness around it before the seraphs were able to banish her. So, they built a fail-safe: this 'dead end' is a door that opens when a seraph speaks his or her true name. Good luck, child, and may the light guide you."

"Thalinya!"
