Zedequette

Zedi-what now?
Zedequette (also spelled Zediquette and Zedekette) is a helpful guide on etiquette / self-help book / life-tip compilation authored by Captain Zedek Mascadolce. It is often referenced in episodes, and a copy has notably been left on Farthum IV to advise the local leadership.
