Keep world-building

Ocean!

V-Sarp rides again...
The center of action is a world which I will 'roll' up quick and dirty.
21 plus 19 is 40% of Earth's mass and I remember that the larger number was sea and the smaller was ocean, which is 52.5% ocean and 47.5% land.
So a small world, a little over half the land area and about three quarters of Earth gravity.
Around 270 m. km^2 surface area, 130 m. km^2 land is about a quarter of the surface area and just a little less than Earth's land area or Mars' surface area.
Is the world a planet or perhaps the moon of a super Earth or giant? The chance is less than 44%, but 84% is 40 over, so no! 8-(
This is a world where the heat engine has died and plate tectonics is dead. The atmosphere is thin, N2 with a little CO2 and argon, unbreathable but just thick enough for people to breath pure O2 through scuba-type gear.
Why is this an interesting place? Is it... Aliens? 8-P
Theres's a 12% chance... 88%
Nope! 8-(
Per-maybe-haps an accidental colony? A ship full of people and their stuff was going somewhere and ended up nowhere? Call it a 79% chance.
46
Finally a winner, I guess... (Nowhere, the joke is they're at the center of 'no and 'where?')
A ship with 34 ahead of 81, or 3481 persons aboard. Seems like a lot. Is is a prison ship?
38% under 68%, so actually, yes. 8-P
What's the chance of something happening? 37% The page rolled a 13%, so yeah, something happened, 8-P!
Going to sort out the land, from 7-4 south (3%) by 82-47 east (35%) is 1.05%, 2.83 m. km^2, Northland.
49-15 = 34%, 92-17 = 75% is 25.5%, 33.15 m.km^2, Midland just north of the equator, which leaves about 90 m, km^2 yet, which would be from the south pole north to 50% and 33% west to 100%, South Continent.
Midland and South Continent just barely not touch on the equator, and the percentages south of the north pole are not linear!
