ESVA's starter is called the Primeiro Registro. It's 1 out of 3, it's permanent — no selling, no trading — and under no circumstance can it ever become a desvio. That part was decided early: the manual describes the starter as "bound to your story," and something bound to your story can't also be a rare pull, or the two identities end up fighting each other.

What I hadn't decided was which three classes to offer. And here I made a reasoning mistake that took me a good while to catch: I was treating that choice as if it were free. I sat down to write the list of candidates — thirteen classes, ÍGNEO, HIDRO, FLORA, CARGA, CRIO, CINÉTICO, GEO, AERO, NEURAL, UMBRA, TÓXICO, VETOR, TEMPO — and started building an aesthetic case for three of them: fire, water, plant, because that's the most recognizable trio in any creature game, and I didn't want to give up the entry-level comfort it gives players who've never touched anything like this before.

The problem is I almost wrote that argument up as if it were a new choice, original to me, when actually I went and checked two spreadsheets I'd already locked in weeks earlier — the roster's class distribution and the 13×13 matrix — and found that ÍGNEO, HIDRO, and FLORA were already different from the other ten, without me ever having thought about it as a starter decision at all.

The number I hadn't seen

The roster distribution (§11.2 of the design doc, if you want to check) isn't uniform, by deliberate design. ÍGNEO, HIDRO, and FLORA have 12 species each. CINÉTICO, VETOR, AERO, and GEO have 10. CARGA, CRIO, and TÓXICO have 8. NEURAL and UMBRA have 7. TEMPO has 6. That distribution was locked in for reasons of bolsa coverage and family structure — nothing to do with "which trio do I want for the starter." But the side effect is that the three classes with the most species in the whole game already happened to be fire/water/plant.

And there's more: the 13×13 matrix locks in a fixed reciprocal relationship among those three — HIDRO beats ÍGNEO, ÍGNEO beats FLORA, FLORA beats HIDRO — a closed triangle inside a thirteen-class matrix where most relationships don't form such a simple cycle. That triangle wasn't designed with the starter in mind either. It was a consequence of authoring the matrix from scratch, without copying anything from the old eighteen-type matrix.

So by the time I got around to "choosing" the Primeiro Registro trio, the choice had already been made twice, by two different systems, without anyone asking "what about the starter?" either time. I didn't invent the classic trio out of nostalgia dressed up as a design decision. I rediscovered a trio that already existed inside my own numbers, because the same properties that make a good opening trio — three strong classes, in a closed-triangle relationship, with broad roster coverage — are the same properties a good progression system needs anyway.

Why this made me uneasy, briefly

For a full day I was suspicious of myself: did I force the roster distribution to fit a starter decision I already wanted to make? I went and checked the chronological order of the documents. No. The class distribution and the matrix lock-in were finalized before I wrote the first sentence about the Primeiro Registro. That's not a special point of pride — it just means the system was consistent enough for a new decision to line up with old ones without me having to force anything. I'd rather have that than have to patch it up later.

What stays bound and why

The Primeiro Registro is never sellable, never tradeable, and never a desvio. The rule exists because a desvio is a promise of statistical rarity — "1 in some very large number" — and an item every player has, guaranteed, at minute zero of the game, can't carry that same promise without cheapening it for the rest of the roster. If your Primeiro Registro could be a desvio, the first desvio on any account would always be the same species, always at the same minute of the game, and that kills the whole reason desvio exists.

Why it never disappears from the game

The Primeiro Registro carries through every "new incursão" cycle along with the rest of your bolsa — level, deriva, the whole collection, none of it ever resets, and the starter isn't an exception to that rule, it's the most visible example of it. I thought it was important to spell this out because, in other games in the genre, the starter turns into a museum piece after the first few hours — you swap teams and it gets left in a corner of storage. Here it stays eligible for deriva, can still carry an aparato, still counts toward profession mastery. The only thing it never does is become a desvio, and it's that one carefully-kept exception that keeps the whole "bound to your story" promise honest.

What I haven't tested yet

The 12/12/12/10/10/10/10/8/8/8/7/7/6 distribution was locked in mathematically, but I've never tested with an actual player whether the ÍGNEO/HIDRO/FLORA trio actually communicates "these three are the strongest opening pick" without me having to write that anywhere in the interface. It's a quiet bet: that the classic trio's familiarity does the communication work on its own, with no help text. The August beta is the first real test of that, and there's a decent chance I'll end up having to write a UI line I'd rather not write.
