R. A. Salvatore Promise of the Witch King The Sellswords — Book 2

TO KILL THE WITCH-KING

When Gareth's holy sword did flash on high

When Zhengyi's form was shattered.

A blackened flame of detritus

His corporeal form a'tattered.

When did victory's claim ring loudly

When did hearts of hope swollen pride

Rejoice brave men, at Gareth's blow

The pieces of Zhengyi flung wide.

But you cannot kill what is not alive

You cannot strike a notion

You cannot smite with force of arm

The magic of dark devotion.

Thus Gareth's sword did undo

The physical, the corporeal shattered.

The Witch-King focus was denied

The magical essence scattered.

So hearken you children to Mother's words

Walk straight to Father, follow.

For a piece of Zhengyi watches you

In dark Wilderness's hollow.
