I was always under the impression that the Altar of Flauts was more to be besmirched then beseeched, but I could be wrong.Still - It could be worth a try. However, I think El Swanno may not be using the correct style of beseechment.
oh great and flatulant; whose winds fortell thy coming before thy arrival; whose breath gives rise to scatological hymn and the whistle of possums; oh ye of great heart and clicky valve; come to us that we might laugh!
