Overview
Firewyrms are wingless creatures said to breathe fire and tunnel through stone and earth around Valyria's volcanic mountains. Accounts of the mines connect them with danger to the enslaved labourers forced below ground. Their development from small young into formidable creatures makes the underground environment a living threat, rather than merely an inert source of precious material.
The texts discuss them through remembered history and in-world scholarship, including speculation about relationships among dragons, wyrms and wyverns. Those theories do not provide a confirmed account of dragon engineering or a reliable classification of every creature found in ruined Valyria. Septon Barth's treatise is a book inside the fiction; the bibliography names Martin's published works that convey these claims instead of pretending the fictional treatise is an independently available publication.
First appearances & development
A Feast for Crows (2005) and The World of Ice & Fire (2014) supply accounts of Valyrian firewyrms. The selected publication history identifies the sources used for this profile, rather than claiming an exhaustive first mention across every short story, companion publication and adaptation. The main novels and their historical companions share a literary setting, but narrators' reports can differ in reliability.
Canon & continuity
The cited reference indexes passages in A Feast for Crows, A Dance with Dragons, The World of Ice & Fire. Those published books are the underlying narrative basis; the wiki is an independent guide rather than an official statement by the author. Direct scenes, remembered testimony and fictional historical compilations are distinguished where they change the strength of a claim.
