The Wyrmling Horde is an epic fantasy novel by American writer David Farland, the seventh novel in his series The Runelords.

Daylan Hammer takes the leaderless humans of Caer Luciare to the world of the Bright Ones for a brief respite, but it is more fraught with danger than they'd imagined.

Despite this, the humans manage to forge an alliance with some of the Bright Ones, led by Erringale, after revealing that the True Tree and an Earth King are found on Fallion's shadow world.

On the shadow world Rhianna flies to the Courts of Tide, seeking an alliance to prevent the wyrmlings from reaching a mountain of blood metal, but they attack her.

Lord Despair also begins taking endowments, from his human prisoners, and must also grapple with the benevolent influence of the Earth Spirit.

However, he is low on blood metal because the Fang Guards at Caer Luciare have Rhianna's rune staff and have decided to rebel against Lord Despair.

So Fallion exchanges endowments of wit with the Emir, promising to teach him the rune for binding worlds, and then subjects himself to Vulgnash who takes him back to Despair.
