Prince-Palatine of the Helvandrian League

The rank of Prince-Palatine is the closest thing the Helvandrian League has to a single ruler, although he is not a monarch and the lords of the League states guard carefully against any possibility of their confederation becoming a kingdom (in fact the Great Charter of the League specifically prohibits him from ever wearing a crown or other trappings of royalty). Instead he is elected by those lords and princes from among their own number. The position is not hereditary, and when one Prince-Palatine dies or steps down, another is chosen. It is for this reason that the rulers of full-fledged League member states are called Electors. 
The Prince-Palatine's official residence is the Palace of Concord in Hakoris, which is the origin of the title. 
Since he can wear no crown and carry no scepter, the Prince-Palatine instead bears his great seal as his badge of rank. This is worn on a heavy, ornate chain around his neck and is used to imprint his decrees and other official acts with the mark of his authority. According to the charter law of the League, falsifying this seal under any circumstances is a capital crime. A new seal is made for each new Prince-Palatine, and that of the previous one is ceremonially broken upon his death or abdication.
