As biomechanical entities, androids can theoretically live forever with the proper repairs. While some embrace this form of immortality, most androids live what they feel is a full life—usually around a hundred years—and then voluntarily instigate a process called renewal, in which the android's soul leaves its body, allowing a fresh android soul to inhabit it. Most people consider this a joyous occasion, metaphorically equivalent to the old android giving birth to a child, and understand that a post-renewal android is an entirely new person who just happens to inhabit the same body. Yet not all people are willing to honor this change or forgive past debts and slights, and such is the case with Iseph.
