The Allbright System - A Sci-Fi Progression LitRPG Story

The answer is probably both—and the UHF has long since made its peace with that.

To understand the Legacies, you have to understand what they actually are, which is something a surprising number of people—including, occasionally, the Legacies themselves—get wrong.

They are not noble houses. They are not political parties. They are not corporations either, though they share characteristics with all three.

What they are, at their most fundamental, is institutional memory encoded on living flesh—families that have been producing Marines for long enough that the knowledge of how to do so has become structural, woven into the way they raise their children, allocate their resources, and understand their own purpose.

Everything else—the crests, the Galas, the centuries of tradition—is downstream of that.

The categories are simple on paper:

Minor Legacies cover the second through fifth generation.

Major Legacies, the sixth through ninth.

Prime Legacies, the tenth and beyond.

What the categories don't convey is the gulf that exists not just between them but within them as well.

A newly promoted Major Legacy looks at one approaching its ninth generation and sees nearly twice the accumulated experience, tradition, and quietly held information—before accounting for the fact that none of those things scale linearly.

Time compounds.

A network nine generations deep is not merely three times more valuable than one six generations deep. It is potentially hundreds of times more valuable. Perhaps thousands.

Most newly established Minor Legacies discover, somewhere in the second or third generation, that knowing how to produce good Marines and knowing how to navigate the political landscape surrounding the Legacy system are two entirely separate bodies of expertise.

The politics exist in the very texture of things—which families take whose calls, which invitations arrive and which don't, the difference between being introduced to someone and being introduced by the right person at the right moment. Resources flow along relationship lines that took decades to establish, and a new Legacy trying to access those flows without the relationships to support them will find the door technically open and practically very difficult to walk through.

Most don't make it.

The majority fizzle out in the second or third generation—not from lack of ability or drive, but from the weight of navigating an unfamiliar system while simultaneously raising children who can actually compete.

Those that reach the fourth generation tend to reach the fifth and beyond.

The attrition is front-loaded, and brutally so.

And yet the UHF doesn't merely tolerate this churn—it almost relies on it.

Even a Minor Legacy that produces nothing but solid mid-tier Marines for three generations before quietly disappearing has fed the UHF's ranks with people who arrived better prepared than they would have been otherwise.

Woven through the Legacy structure as well are the Thals and the Grand Thals—where the system's relationship with the UHF's administrative apparatus becomes most visible.

A Thal is, in practical terms, a System Lord: A figure granted tentative military and civilian oversight over a cluster of systems, working alongside existing planetary governors and UHF structures.

It is not absolute authority, nor was it ever designed to be.

It exists because a Thal family has skin in the game in a way a rotating administrative appointment never quite does.

They live there. Their children grow up from there. Their Legacy is built there.

When things go wrong, it is their name, their Legacy, attached to it.

The Grand Thals operate at a higher level still—appointed directly by the O-13 Council, drawn almost exclusively from Prime Legacy families, holding authority over entire Sector Clusters as the civilian counterpart to the regional Proprietors.

Two figures of substantial authority, overlapping jurisdictions, different primary obligations, expected to function as partners. In practice, it works about as well as you'd expect—sometimes excellently, sometimes not at all.

Yet perhaps the most consequential function the Legacies serve—and the one the UHF is most careful never to state explicitly—is as a research and intelligence apparatus the military complex could never fund at the required scale itself.

Knowledge of rival Builds, undocumented System mechanics, Ability interactions, Tier progression patterns—all of it researched, compiled, and quietly traded by families with the resources and motivation to do it properly.

When the UHF wants access to that research, it offers favours, introductions, and early access to Command decisions in return.

Neither side discusses the arrangement directly. Both sides understand it completely.

It is not a clean system.

It was never meant to be.

It simply works… Until it doesn't."
