From the publisher blurb:
As your characters set off into the universe, the right backdrop - the star system or systems they're voyaging through - can help their story be told. It's like finding a home - the neighbourhood has to be right for you: Is it close to the shops? How does the neighbourhood look?
Is that smoke?
So the aim of this booklet is to give you a run-down on a realistic star system, centred on a massive, blue-white sun - in particular, how it would be experienced from an Earth-like planet in its habitable zone. The star, also known as a type A5: A fairly rare, very hot star several times bigger, much heavier and much brighter than our Sun, that lives less than a tenth as long as our Sun. Its system of worlds is far wider spread than ours, needing not just years but decades or even centuries to travel between with today’s technology - but, despite its short life, it's a calmer landlord than our sun throwing out far fewer dangerous flares and radiation storms. Beyond the broad themes you can set specific details to your needs - for example the number and type of other planets and the galactic neighbourhood. The booklet goes into:
