Lava Lindwyrm(updated)

"Lava Lindwyrms dwell deep within the planet's crust whilst immersed in extreme temperatures. When surfacing, they leave devastation in their wake as their tunnels allow molten rock to rush up and create new volcanoes. Their young can be found congregated around such areas, bathing in the shallow streams of magma. Though Lava Lindwyrms inadvertently leave wreckage behind whenever they travel, they are a boon to the various dragon breeds dependent on volcanoes and volcanic activity."
