You entered a cave in the enchanted forest filled with mythical creatures

You didn't know what was in the cave but you entered it regardless because you were tired

When you enter inside the beauty if the cave took your breath away it was filled with beautiful crystals and plants there was a glow in the cave it was a giant cave

The was also a waterfall inside but then you saw a figure sitting in the middle of the cave

What do you seek human?

It was a dragons lair
