"Ahhh, so there is a secret entrance," Oloc says with a smile. "My guess is we move the statue's arm to release the mechanism opening the door. What say you? Shall we give it a go?"
Gaven replies to Oloc, "Shall we try to trigger both the altar and statue at the same time?" The cleric makes sure everyone steps away from the possible trap door in the floor.
Duran nods in agreement and steps back as the others try and activate the trap door.
On the count of three, Oloc pulls on the statue's arm, and Gaven presses the square on the altar.
The square piece on the altar does not move at all. It yields to neither pushing, pulling or twisting. Gaven notes, however, that the square section does seem to cover a hollow space, unlike the rest of the altar's surface, which seems quite solid.
Oloc has better luck. The statue's arm descends slightly with a faint scraping of stone on stone. As the arm is lowered, the font is suddenly filled with a clear liquid.
How the liquid entered the font is impossible to tell. There seems to be no spigot or opening from which it poured. It merely appeared in the basin when the statue's arm was moved.
A pleasant fragrance emanates from the transparent fluid. The scent is difficult to identify. If the sunlight of a fair spring day had a scent, the perfume of the liquid could best be described that way.
