Event System
See Data Model for the Event, EventEntry, Stage types
this section builds on.
Death Probability per Stage
Before every event, a roll decides whether the person dies. A minimum number
of events per stage must happen before death is even possible. Past that
minimum, the probability rises with a magic_factor.
death_probability = death_at_stage[stage]
Generate events until the person dies.
minimum_events = events_per_stage[stage]
if current_event_count > events_per_stage[stage]:
death_probability += (current_event_count - events_per_stage[stage]) * magic_factor
