Each of the reflectors have a falcon symbol in the middle of them. When the objects are lit in a specific position, they make a constellation of Horus's symbol--the bird. The constellation opens to the 'final chamber,' which would lead to the Mask Of Anubis.
One wall in the tunnels had a 'zodiac,' which would help one to find the reflectors; however, it was only half full. A page in The Book of Isis had the full zodiac. This helped both Sibuna and Victor find the reflectors.
List Of Reflectors & where to find them
- The sun shard in Vera's Room/Attic.
- The mirror in Sarah's music box in Nina and Amber's Room.
- Doll's Eye (Part of Face) which was stored in the attic.
- Cup/Goblet in the kitchen cabinet.
- Victor's pocket watch in Victor's Office.
- Mosaic Of Osiris, originally in the hallway of Anubis House, but moved to the Frobisher-Smythe Library.
- In Season 1, the sun shard helped Sibuna figure out one of the riddles: "where daytime ends at midday through tears of glass the eye shall see". They looked at it, and realized that 'midday' was really sunset.
- The message spoken earlier by the doll helped Sibuna figure out where to find the spare key to the Mask chamber.
- The box can be seen in House of Hush / House of Spies / House of Sting / House of Never / House of Forever.
