A few months back I asked a question of one of the Facebook Traveller groups that I read. I have a scenario in mind where the PCs are exploring an abandoned habitat. No specific setting, no specific arrangement. Just some kind of colony. The idea may have grown out of the tables in Stellagama's Pirates & Privateering source book, which lists abandoned space stations as a random encounter.
The question was: Why did the colony fail? Much to my delight, the answers poured in. I have collected here the bulk of the answers (deduplicated for near identical answers) and arranged them in a D66 table. To roll D66, roll 1D for the 'tens' digit and a second 1D for the 'ones' digit.
If you have any ideas that don't appear on this list, share in the comments!
D66 Reasons why the Colony Failed
11 Pilgrimage site for some religion that was later deprecated as a forgery
12 Fast-acting or slow-acting contagion (bacterial/viral/fungal/parasitic)
13 Mining site, better yield found elsewhere and everyone moved.
14 Mining site, ore vein tapped out
15 Colony set-up was a scam. Shells of buildings only, no infrastructure. Scammers on the run.
16 Environmental factor not initially detected caused health problems (i.e. death)
21 Temporary facility during a war, abandoned in peace time
22 Resource point for a project nearby, abandoned when resource no longer needed
23 Hostile neighbors
24 Predatory animals attacked settlement
25 Research base- abandoned when research was concluded
26 Mass murder by a resident killed too many to continue running the colony
31 Solar flare/radiation spike forced evacuation.
32 Financial backer was bought out, new owner did not want to continue funding

|Honey, who left this window open .?. . WHOOSH|
