his jorts, his jants his joots
This is Onyx, the older of the twin brothers. Like Jay said, they were abandoned by their single mother when they were very young, and forced to live on the streets as thieves. They're incredibly good at charming others into nativity, using their good looks and flowers to win the hearts (and wealth) of many unsuspecting kalons. Because of their rouge nature, they never stay in one place too long and are constantly traveling.
Onyx has a brother complex and rarely lets anyone close to Pyre. The two are practically inseparable, even if they are very different in personality.
While Pyre tends to keep to himself, Onyx is more charismatic and optimistic. He takes the role of leader in most of their "operations", but Pyre is always there to keep him from being too reckless.
