‘I saw the Father of Dragons, Glaurung—twice’, says Celebrimbor. ‘I saw Gothmog, the Lord of Balrogs. They carried the dark flame of Morgoth inside their hearts. When it was strongest in them, it was as hot as a volcano, as hot as fabled Mount Orodruin in the Southlands! Where they went, the rocks beneath them melted into a trail of black glass... They were terrible, Narvi.’
The hearth-fire flickers, throwing an abrupt shadow on the cave wall. Narvi shudders inwardly. Nightmares of the First Age!
‘There are no balrogs here,’ he murmurs, soothingly, ‘and no dragons. We have peace.’
A/N: The word obsidian does not occur as such, but as obsidian consists of volcanic glass (Wikipedia again!), I hope this will be acceptable.
