Tam, you see no obvious traps on the pyramid; whatever magical properties the pyramid has, they are passive / protective in nature. All that is left now is to insert the triangles into their respective slots. (Remember, the triangles are the non-active form of the magical devices that you've found so far. Saying the command word for each active device will cause it to revert to triangle form.)
EVERYONE: What do you do?
