"Near the Lost City's plaza is a stone "temple". It is avoided by Most , as it is not an
Altrusian ruin but rather was built by some other long-lost agency.
Inside the temple is an empty antechamber with a sundial set into the floor,
somewhat of an oddity since the sun doesn't reach that far into the room.
There is a solid stone door at the back, and at the top of the door frame is a
sculptured relief high on the wall of two human hands touching; one hand is convex, the other concave.
The door only opens when a someone puts his or her hand into the concave relief.
Inside is a crystal-illuminated chamber with the largest crystal matrix tables.
There are also several humanoid statues. Farther away from the Lost City is
another smaller complex also called "The Temple". This other Temple is perhaps of
Altrusian origin: its decorations include the half-sunburst symbol seen over the entrances to the Lost City.
They wound up using this temple as their primary shelter in the third season.
The mystery of the Builders and their Temple was never explained further."
