Titan-Wyrm War

History records two things called "Titan-Wyrm Wars". Both happened during the First Age.

The First Titan-Wyrm War

No one's quite sure why this started. All we know is that the Titans and the Wyrm (or large portions of them) fought for a millennium or so. Creation vs destruction--maybe the argument was over aesthetics? No one knows. All that's known is that the Titans lost, but the Wyrm did not follow up and destroy their enemies. Maybe they were too battered to continue?

Fallow Time

Between the First War and the Second War was a fallow time, when the survivors regrouped and rebuilt their civilizations.

Near the end of this time, the Titan Conclave gathered to prepare for what they considered the inevitable resumption of the war (which they denied they had lost), creating a self-fulfilling prophecy. They began work on the Orb of All Might--the empowering of which created the dwarves from much of the titan race (those the Conclave considered "lesser").

The Second Titan-Wyrm War

A frantic attempt to stop the completion of the Orb, Titans against Titans, dwarves, aelves, goblins, and wyrm. So not really titan-wyrm, but Titan Conclave vs everyone else. It failed...or succeeded? In the end, the Orb was activated, shattering both runic magic and true sorcery. No more would mortals wield the true words of creation directly. In the backlash, titan became jazuu and giant-kin; wyrm became dragons.
