Windcaller Lizardfolk (5e Race)

The windcallers are a subrace of lizardfolk native to mountainous regions. They worship the mountains themselves and the prevailing winds that surround their home.
Windcallers are cautious, xenophobic, and paranoid; it's rare that they allow outsiders into their homes. They are far smaller than their swamp and desert-dwelling brethren.
Some windcallers choose to leave their close-knit communities to learn more about the world around them. Of course, their fellow windcallers see these explorers and adventurers as mad.
