"The Lannisters send their regards. "

House Lannister of Casterly Rock is one of the most powerful and richest families in the seven kingdoms - and for a good reason. No one crosses Tywin Lannister.

The Rains of Castamere is a song of destruction and victory waged against the rebellious House Reyne. The latest episode of HBO's Game of Thrones showed the same fate for the Starks. Nothing is more tragic and epic than a slaughter in a wedding. As the doors closed and the song started playing, the dawn of realization on Catelyn Stark's face was enough to tell everyone - the Lions are at it again.

The Lannister weddings were nothing compared to the Red Wedding. Walder Frey was prepared to break to break the sacred house of hospitality. He wanted to avenge his honor and he brutally got it so. Twyin Lannister is as implacable as ever and Walder Frey was a petty tyrant. He never got into terms with forgiving those who cross him even on his daughter's wedding day or on his wife's life.

"The wine will flow red and the music will play loud and we'll put this mess behind us," he said. A few moments later, the song plays.

And who are you, the proud lord said,

that I must bow so low?

Only a cat of a different coat,

that's all the truth I know.

In a coat of gold or a coat of red,

a lion still has claws,

And mine are long and sharp, my lord,

as long and sharp as yours.

And so he spoke, and so he spoke,

that lord of Castamere,

But now the rains weep o'er his hall,

with no one there to hear.

Yes now the rains weep o'er his hall,

and not a soul to hear.

(Refrain 'The Rains of Castamere')

Roose Bolton and the Freys hid under the Lannister name. Breaking the guest right was not an issue and so is politics, betrayal and ascension to power. The song of Castamere refers to the battle between the heads of the House Lannister and House Reyne. Lord Reyne did not pay their taxes or loans. He was ignorant of his duties to the Lannisters. It goes against the family's infamous line - 'The Lannisters always pay their debts.'

A house that has a similar Sigil, House of Reyne was already on its way to downfall. Westeros is known for protected families. Similar sigils meant their allegiance with their lord's houses. Lord Reyne did not honor that. The song was written not to mourn over the destruction of the house but to celebrate the victory of the Lannisters.

The song marked another bitter ending to a family - this time one of the most well loved families in the story, the House of Stark.
