a balance, fairness, or stability
Original Dramatica Definition
Equity is balance. The Equity characteristic makes a character want everything to work out fair and square. He will spend his time trying to maintain balance and will judge the acceptability of a situation by its apparent equilibrium. On the downside, he may not realize that without inequity there is no motivation and hence no progress. Also, there may not be enough to go around. By "robbing Peter to pay Paul" he might be moving resources back and forth in a way that stresses the whole system which might crumble from the strain.
syn. balance, fairness, parity, equilibrium, level, even
