The way Game World reacts to Player action is daytime-dependant sometimes.
Astor supports different time flow scales (and even real time). Additionally, special scripts can be launched based on Game World age, date or time producing global events.
Astor shows time flow using stars, e.g. Sun, Moon. Stars count is unlimited and even different location can have different stars count and types. Each star has own trajectory, rotation speed, light intensity, etc.
