A Space Tramp's Guide to Star Classification

This is your first time on Fargone Station, having just stepped off a large biostuff transport with a few passenger cabins bolted onto it.

Rifling through parcels and envelopes, they toss several items over their shoulder, and this booklet lands at your feet.
