Basically, exactly what it says on the lack of a cover. Take your handful of 6 or 7 standard RPG dice (d4,6,8,10,10 (marked as tens, if you don't like rerolls),12 & 20), roll them, pick up and re-roll that d4 that you dropped under the table, refer to the single page and in less than sixty seconds you've noted down:

• alien controlled
• orbital ring
• in an exotic location (a comet diverted into interstellar space),
• acting as a communications relay
• with a staff of tens,
• that are having repair issues.

The d10-as-tens is used if the standard d10 rolls "10: exotic" - so you don't need to roll again and burn precious kilocalories. Above, the second roll was "Comet". There's a rule to divide by x if your outpost type doesn't match the location - e.g. subsurface tunnels in a gas cloud - although maybe that's even more interesting... What are you up to this time, Q?

From this basis, just fill in from your imagination and campaign background, which should only take a few minutes.

• I dredged up "in interstellar space" for a plausible but exotic comet situation.
• I decided to roll a d8 (for tens) and d10 (for units) to get sixty for the actual population.
• Why put a base around a comet? Presumably easy access to water and other ices, and maybe small amounts of minerals. So the repair issue they have is clarified to become they can no longer repair the system that extracts water, carbon dioxide, ammonia and methane ices for life support and organic feedstock.
• Why a ring? So there's no dead spots for communications caused by the comet, or to provide a compound antenna kilometres wide. And maybe - if it's miltary - each ring component is smaller and harder to detect than a single large base.

So now, depending on my campaign I have:

• an enemy installation, (perhaps a listening post) that needs assistance - do the PCs assist, perhaps on condition of surrender, or try and sieze or destroy it?
• Or maybe the Kr'ZZit Communications Net supports this whole galactic arm, and rendering assistance - well, lets just say when that message just needs to go through two adventures down the track - it will. Especially if it needs to go through "discreetly".
• Or perhaps this is a first contact civilization setting up a hypercomms network to support their first interstellar colonies, that your PCs stumbled onto just past the edge of known space. Will they start a war with these strange looking "Terrans", or introduce them to the benefits of galactic society?
• or many more, from just "one roll".

Location and encounter generation tables aren't anything new, but this is one-page to slide into your GM folder or onto your tablet or laptop, as a a pretty amazing tool for that unexpected side-quest or to fill out a session that ended sooner than expected, or that you had no time to prep for. I think it deserves 5 stars - that it's free means what are you waiting for? The galactic black hole to evaporate? Stop reading this waffle, and go get it now.

This is a review of the quality and coverage of the PDF product. It isn't a review of the content (i.e. the adventures and associated features).

The scan is sloppy. Usually in focus, but often the pages are skewed and there's a bit of bleed-through on pages that had pictures on the reverse of the original page (mainly cosmetic and doesn't affect the functionality) but in some cases the edge of the page is missed, leaving off text - and this happens on several pages, including some giving stats for dragons and PCs - so this product is missing stats on the most important characters. One map is skewed so badly one corner is missed and some of the other edges technically are lost too. The final page, of cut-out paper standee NPC/Monster figures, has the top and bottom row of figures cut off halfway. I haven't checked the colour multi-page maps for missing pages/edges, etc. Might or might not be OK.

Given this is about 80 pages long, it can't have taken much more than 20-30 minutes to scan. Taking an extra minute or two to rescan the skewed and cut-off pages - or even just the cut-off ones - surely falls within the budget of WOTC? Even if they didn't give the job to an unpaid intern? Not even enough quality control to scroll through the PDF and note the cut-off bits before it gets published?

I'm sure an experienced DM could get around the missing information. And you could possibly draw your own figures for the half-missing ones. But for a new DM (which these are aimed at) it could be a blocking factor in playing what they've paid for. And given the source isn't just some random person on the Internet scanning a copy and dumping it on a pirate site, it seems a bit cheap and nasty.
