The cleric reaches his hand into the altar compartment and pulls on the handle. A blinding flare of white energy rushes up out of the compartment, bathing Gaven's torso in pale flame. The cleric of the light seems to feel no discomfort at all.
The flame slowly dies down again, and there is a second of silence. Then you hear the sound of grating stone, and the portion of the floor behind the altar which Duran had previously identified gradually slides open.
Through the dark opening in the floor, you see a stairway down ending in a corridor that extends out of sight to the north. At the bottom of the stairway is another lever.
Duran asks Gaven if it is appropriate to take some of the water in basin for their water skins, and Oloc agrees with the suggestion. Gaven believes that taking some would be fine. The Light does not offer what is not meant to be taken.*
Oloc also asks if anyone has any holy water, thinking perhaps that would work on the stains.
*This is based on character knowledge that Gaven would have as a cleric.
If you take some of the water from the font, please state that (just to confirm).
If you descend, please let me know how many torches/lanterns you have lit and who's holding them.
It has been suggested that Buckeye, Sophie (animal handler), Bill (porter/torchbearer), Ollie (porter/torchbearer) and Gweneth (merc) remain topside in the church. Please confirm, sometime before you descend, if those are the NPCs you want to leave in the church.
If you were to leave the proposed NPCs behind, you might have a marching order looking something like this (vs. the one currently posted on the PC Info Page):
Scouting: Karnak (7/7)
Front Rank: Gaven (12/12) Almo (10/10) Duran (11/11)
Second Rank: Filbert (6/6) Oloc (6/6) [Light?] Wally (4/4)
Third Rank: Stan (3/3) Jack (4/4)
Also, the corridor is 10' wide, so you could take the mule with you if you wished. Upside: you need leave no one behind; downside: the mule will "clop-clop-clop" a bit as you walk, so you will be less likely to surprise anyone you meet.
