What if a Warlock rode a motorcycle?

D&D 5e presents a class - the Warlock - that exemplifies a cool concept done wrong by lack of rules support.

There are no mechanics associated with a D&D warlock's relation to their patron. No metagame consequence if the player fails to follow through on their character's obligations. Indeed, even in the fiction of the character creation there is not much explanation of what a warlock has to do at their end of their pact. Really, a warlock should carry as much fictional burden as does a paladin. A pact is simply a different word for an oath, and both the warlock and the paladin pledge fealty to an entity as payment for their powers.

That brings me to this game, Liege. The game runs on Jason Tocci's 24XX engine, but the key innovative mechanic is a Fealty die. It is a kind of usage die for supernatural power, attained by invoking the character's immortal liege. Even if the character acts to further the liege's interests, the invocation may displease the liege. There is always a risk of condemnation for presumptuous and excessive reliance on the liege's power. But with that power, impossible things can be accomplished!

The game's Gear list combines medieval and 20th century items; swords and shotguns, horses and motorcycles. The setting is implied to be a timeless mashup of motorcycle monks and contemplative bandits, all devoted to vigilante-style righting of wrongs they perceive. What those wrongs might be, and how to set them right - and whether the act of righting them will please or infuriate the characters' liege(s) - those are questions that one must play to find out the answers.
