The burning means that the lord is back -

Reformed and ready to launch a new attack.

But first he'll want to find his faithful few,

Good servant or traitor - which are you?

Just thirteen years ago you cheated and lied,

Your allegiance to the dark lord was denied.

You swore you were made, Imperiused you said

You wish that was true, as you slip from your bed.

For years your wife believed your story of woe,

Now you beg her forgiveness before you go

To plead with your master to forget and forgive,

To believe that you're faithful and let you live.

You were the first to fall at his feet and crack -

You grovelled and begged him to take you back,

He did but wanted thirteen years repayment first,

To start your debt, with Crucio you were cursed.

You hoped and prayed and writhed and rolled,

You tried to win him back with a prophecy foretold.

He acted on your word which turned out to be wrong,

The agony of his punishment seemed to last so long.

You were forgiven again and stood by his side,

In the midst of the battle you could no longer hide.

You placed your eggs in his basket which broke,

A child's choice that you could not revoke.

Your master was lost and so was the war,

Your marriage and life could be lived no more.

All you ever wanted was some peace and to be left alone

No peace - but alone is a given, when Azkaban is home.
