Like all Umbra, Sisyphus has pitch hair and deep-set eyes swallowed in darkness save for a pinpoint of light, like distant stars. Alone, they tell nothing, but speak volumes when offset by a twist of his lips. He is pale and thin, his brusque stalk belies a mass and weight not apparent on his frame.
Sisyphus is a ruthless, unpredictable nihilist, although far more intelligent and sagacious than initially apparent. With a black wit and ironic sense of humour, he finds no reason to question fate, proving him adaptable and languidly at ease in any circumstance. Prone to arrogance, he considers his savage qualities superior, setting him apart and above other people; he embraces, indulges, and cultivates the dark lusts; otherwise, he lacks a driving force or focus. He represents great, if nefarious, bloodlines muddied with the petty destructiveness of the fearful turned mean.
Sisyphus is abetted as much as he is hindered by his openness to reason, his curiousity, that he is not indifferent to other opinions. These things, combined with his incisive mind and decisive manner, make him suitable for a role of leadership; they also make him (to his mind) weak and fallible. He is searching for something solid to latch on, and only then can he throw away the lesser parts of his character.
