A few thoughts on how specters give characters opportunities that they could not have had in life due to their environment, circumstances, and personality:
While alive Duke was a famous artist, always in the spotlight of the crowd. After his death he gained the ability to become invisible.
Pluto's luck was always against him in life so after death he brings bad luck to others.
He couldn't escape his father? His spectre gave him the ability to move in the blink.
While alive Eulalie failed to fulfill her dream but after death she acquires the ability to embody any fantasy.
Her friends abandoned her in favor of their own dreams? Well now Eula uses her chimera powers to absorb other people's dreams.
Berenice spent her life in drunk parties and her fondness for alcohol was blamed for her death. So after Berenice intoxicates her victims with her bites making them act drunk.
While alive Morella couldn't defend what she believed in but after death she has a shield and a sword.
While alive as a servant Ada was always forced to remain silent but after death she has a piercing scream.
She did not dare to raise her eyes until asked? Well her spectral gaze is both mesmerizing and terrifying.
Will was nobody in life. After death he can be anything.
While alive Montresor was completely controlled by his mother and church but after death he subjugates others' wills through deals.
The church brainwashed him? His spectre can get into people's heads.
While alive Prospero was a hypochondriac doctor. After death he is accompanied by an army of rats, known carriers of disease, and he can cause others to feel ill.
While alive Annabel was forced to get married so after her bride's kiss brings death to the chosen one.
She was forbidden to cry in public? Lady in White spreads an aura of longing and loneliness, causing everyone to cry out of despair.
Lenore blamed herself for surviving while Theo died. After death she gains the ability to take the suffering of her loved ones upon herself.
