Flight Rising includes a wide variety of Familiars. They are sort of like pets for your dragons. Click on all of your Familiars every day to get Treasure. You also get a chest when each Familiar levels up. The Citrine Cave Jewel is a Familiar that I got because it was hiding in a random chest.

Citrine Cave Jewel: – Familiar – Colonies of these tiny lizards live deep within Dragonhome’s cave systems. The glowing fungus they consume contributes to the lizards’ bioluminescence.
