The lizardfolk don’t see the settlers of Wyrmwatch as any different from the Poison Dusk, who also seek to remove dawn shards from Q’barra. The lizardfolk are ruthless when they raid the town’s mines, leaving no survivors and destroying what mining equipment they find. Though they have good reason for doing this they have been unable to communicate the risk to the settlers. If someone could explain the lizardfolk’s aggression to Elder Nevillom, he could be instrumental in resolving the hostilities. The lizardfolk don’t understand that the settlers are unaware that they are weakening Masvirik’s prison. In this way, the Church of the Silver Flame and the Masvirik’uala are aligned. They just don’t understand that they are on the same side in this conflict.
This is where the player characters come in. The lizardfolk have difficulty communicating with the settlers of Q’barra, both in New Galifar and in Hope, and they need people who can act as translators. Elder Nevillom would almost certainly champion their cause were they aware of what is at stake, but how might other communities react?
It’s entirely possible that greed would win out over self-preservation. The settlers already view the lizardfolk as superstitious, so perhaps mining and prospecting would continue regardless of the threat. House Tharashk has already called for New Galifar to go to war with the lizardfolk, and escalating tensions in Hope only add fuel to this fire.
If Elder Nevillom is made aware of Masvirik and the Poison Dusk, and of the threat they represent, it’s possible he would request the support of Flamekeep or Newthrone to put a stop to the dragonshard mining. Jaela would almost certainly support Elder Nevillom and the lizardfolk, but how might King Sebastes react?
