Circle of Savagery

Source: Children of the Dragon

While the more civilized Sharptooth lizardfolk are famous for venerating their ancestors, most lizardfolk tribes are more pragmatic and don't see the practical advantage of such a tradition. However, these tribes do possess many powerful druidic spellcasters, many of whom are part of a secretive druidic circle; the Circle of Savagery. These lizardfolk druids carry within their blood, whether by heritage or ceremony, the memories of the ancient "terrible lizards", the dinosaurs. Through this they are able to summon the spirits of these terrifying creatures, or transform into one outright.
These summoned allies of nature look just like their ancient selves, and can also bleed and suffer pain. However, once it dies, or the druid loses its concentration, it vanishes.
Unlike the more civilized Sharptooth tribes, they don't gain their divine powers through the veneration of their
"dragon" ancestors, nor are they able to take their form.
Instead, they use their druidic powers to draw upon the memories of their ancestors to summon and transform into prehistoric beasts.
