Remember how you lit the first burial chamber? This one works the same way. Mostly.
Hint 2
Walk past the black cat statues and look for a lamp fixture in the left wall, then add lamp oil and use the lighter.
Hint 3
The resultant mirror puzzle is the same general idea as the last one -- the light reflects off a series of mirrors until it hits the last light --
Hint 4
-- except this time you have to place the six mirrors yourself. No biggie; in fact, you can do it using only five mirrors.
Hint 5
To place a mirror, pick it up from the stack at the right and put it in one of the available holes. If it's tilted the wrong way, move the mouse a little till it turns into a circular arrow, then click to turn the mirror.
