Statues of the Lost Necropolis

While exploring an ancient necropolis of dead humanoid creatures with skulls shaped like the heads of reptiles, the party came across the following statues, all about 6-7' tall, located in various places around the city of the dead. Each statue was made of stonework such as marble or obsidian, of a particular color, and stood on a similarly-colored pedestal. Each pedestal had, carved into its front, a particular symbol. Kleeck copied each statue description and symbol into his journal:

Statue color	Statue substance	Statue Appearance	Pedestal Symbol
White	Marble	Humanoid crocodile w/ridged tail	Circle with line down the middle and lines radiating out of one side**
Black	Obsidian/Stone	Cobra-headed, snake-tailed woman	Cloud w/lightning coming out of it
Light Blue	Marble	Seated dragon w/sapphires for eyes*	Dragon head profile in silver
Dark Red	Stone	Dragon, wings spread out as if taking flight	Flame
Pink	Marble	Serpent headed, snake-tailed woman	Dove
Blue	Marble	Dragon w/tail whipping out, crown on head	Hour glass
Red	Marble	Snake rearing up ready to strike	Harp
Dark Blue	Shiny Stone	5-headed dragon with barbed tail	5 dragon heads arrayed in a circle like a compass

*Trying to take the sapphires turned Bandua into a gaseous form for 10 minutes.
