Within the Dark Kingdom of Jade, an Eunuch is a wraith that has been stripped of his will and now basically serves as a living notepad for the Imperial Bureaucracy, as paper and therelike are extremely rare in the Shadowlands. By command, a Eunuch is able to recite every piece of information stored within him.
The method was discovered by Zhang Kunyi, one of the ministers of Yu Huang's Protectorate, and quickly established itself within the realm of the Jade Emperor. As they proved themselves extremely useful, every branch of the Imperial Bureaucracy uses specialized Eunuchs for their own purpose, such as the Abacus of the Jade Censors or the scouts of the Imperial Army. Some also serve as public sources of information and are placed in central locations within a Necropolis to deliver local news or imperial creeds. Within the Jade Palace, a gigantic Eunuch Central is seated in which all information about the Yellow Springs is contained.
Every Eunuch is normally moliated into a form that has the most effective use for him, in general this involves severing the arms and opening of the chest for rapid approach by his owner.
