Rarity

The Rarity Index: How We Decide Which Worlds Are Legendary

8 April 2026 · 3 min read

Common
60
Rocky worlds, ocean worlds, tundra, desert.
Uncommon
30
Gas giants, ice worlds, storm systems.
Rare
20
Crystal worlds, volcanic extremes, anomalies.
Legendary
10
Void worlds, twin suns, ringed giants.

Of the 120 worlds in the Space Estate catalogue, only 10 are Legendary. That's 8.3%. If you pull one, you'll know immediately — the gold border gives it away before you've even read the name.

But rarity isn't just a number. We didn't pick 10 at random and label them gold. Each Legendary world satisfies three criteria: cosmologically unusual, lore that stands alone, and a visual identity that couldn't exist in the Common tier without feeling wrong.

Void worlds are the most extreme example. They're dark, ringed in energy, and described with language that borders on unsettling. Pulling one feels different. That's intentional. Twin-sun systems made the list because a planet lit from two directions is immediately striking — no one sees that card and thinks it's ordinary.

We won't rebalance the catalogue. The 10 Legendaries are fixed. No seasonal variants, no limited editions, no second series. The distribution you see is the distribution that will always exist. If you pull a Legendary, it stays rare — because the pool it came from doesn't change. That permanence is part of what makes it worth something.
