An elite military unit much like the Paladins or the Enders Corps, the Drakeguard is the Servitor army of the Champion of Dragons.

The hierarchy breaks down thus:

The Marshall of the Drakeguard, Greater Dragon General - the Champion of Dragons

Rainbow Dragon General, Hand of the Champion of Dragons

Black Dragon General

Blue Dragon General

Red Dragon General

Below this are the Dragon Colonels, Dragon Majors, Dragon Captains, Dragon Lts., Dragon Sgts., and Drakeguards. Only the generals and colonels are Servitors. Every member of the Drakeguard fits into one of the above units (Rainbow, Black, Blue, or Red), but the most elite earn spots as members of the Greater Drakeguard, who are also Servitors.
