Masks of the Great One
Iron Scale clan
The Iron Scales are a clan of lizardfolk. Under the subtle influence of Old Gretchen the hag, their chieftain Harka led them on an expansionary campaign. They killed any lizardfolk who refused to join them. They acquired metal weapons from the party, giving them yet another edge against their foes.
In the end, the clan was laid low by the betrayel of Old Gretchen and repeated encounters with the party.
