Where to look
Where in a galaxy should you look for class S items? Anywhere you like: there is no golden ring. Tools grow all the way out: a median system at the core offers about 220,000 against about 290,000 at the rim, and 23% of core systems are Uncharted, against 12%. Wealth moves what you find far more than distance does, so pick a system for its wealth, not for how far out it lies.
Rings of the galaxy
Tools grow slowly on the way out. The mean of class S stays high out to 500,000 ly because pirate systems crowd there, 13% against 5% at the rim, and a pirate class S is weak in damage, as multitool classes explains. The median of class S climbs slowly. Wrecks stay about level.
Compared with the core, 100
| From the core | Tools, median system | Class S, median | Class S, mean | Pirate | Uncharted | Wrecks, median system |
|---|---|---|---|---|---|---|
| 0 to 100,000 ly | 217,185 | 1,862 | 3,593 | 15% | 23% | 3,481 |
| 100,000 to 200,000 ly | 228,224 | 1,842 | 3,432 | 13% | 21% | 3,582 |
| 200,000 to 300,000 ly | 233,099 | 2,004 | 3,604 | 14% | 20% | 3,658 |
| 300,000 to 400,000 ly | 241,576 | 2,139 | 3,632 | 14% | 17% | 3,759 |
| 400,000 to 500,000 ly | 249,056 | 2,300 | 3,638 | 14% | 15% | 3,823 |
| 500,000 to 600,000 ly | 274,762 | 2,399 | 3,176 | 7.4% | 13% | 3,960 |
| 600,000 to 700,000 ly | 288,037 | 2,459 | 2,940 | 4.8% | 13% | 4,037 |
| Over 700,000 ly | 287,946 | 2,475 | 2,971 | 5% | 12% | 4,015 |
Stars
The stars themselves are spread evenly: a median voxel holds about 590 stars at the core and at the rim alike. What changes is how many systems hold life, not how many stars there are. There are no spiral arms either, from the core to the farthest voxels at the rim and through the whole height of the disc. Maps that draw the galaxy as a glowing spiral with arms and dark gaps between them are pretty, but the stars are not laid out that way.
| From the core | Stars per voxel | Bodies | Yellow stars | Purple stars | Uncharted |
|---|---|---|---|---|---|
| Under 200,000 ly | 592 | 5 | 52% | 12% | 22% |
| 200,000 to 400,000 ly | 598 | 5 | 58% | 12% | 18% |
| 400,000 to 600,000 ly | 596 | 5 | 66% | 12% | 14% |
| Over 600,000 ly | 594 | 5 | 68% | 12% | 13% |
So the choice comes down to one star, and systems shows what a star can hold.
