Castles

What can one build them with?

Castles are built out of Iies
That to suit one's inner drive
One might ask "Is that a crime?"
I'm just a fool, so who knows?

Castles are built out of shit
That to suit for one to fit
One might ask "Is that so bad?"
I just jest, who knows?

Castles are built out of me
That to suit just what I see
I might ask "Where is everyone?"
The king, a fool, who knows?

They've all gone, subjects of thee
Lost for all eternity
No more questions, no more asking
"Who knows?"
