Leadership (Ld) indicates a character's ability to lead others.
A character with high Ld is naturally charismatic, inspiring confidence and loyalty, whilst a character with a low Ld may be rather indecisive.
This characteristic is expressed as a percentage of 01-100%.
For tests, Ld reflects a character's ability to command respect and loyalty and, in some circumstances, to obey orders and follow instructions given by a superior.
