A recurring character type in the Fire Emblem series that is often good until some point late
in the game. A Jeigan character is often a promoted unit that joins on the very first chapter, and is used by players, especially
experienced ones, to keep turn counts at a minimum.
Jeigans are often underrated by players who care more about how a unit's stats are at
the highest possible level rather than how they are in certain chapters at certain levels.
