OBOL & ASH
Ten thousand souls. You do not buy passage — you answer for it.
The Ferryman decides who crosses free.
01 The Premise
Obol & Ash is a 10,000-supply, fully on-chain ERC-721 collection on Ethereum. Every soul lives in contract storage — art, metadata, and traits are all rendered on demand by the contract itself. No IPFS. No external hosts. No servers that can vanish.
The collection is built around a single idea: you are not collecting, you are ferrying. Every Crossing is a real risk and a real reward. Every passage is earned — not bought.
02 The World Between
The Ferryman of the River Styx is older than memory. He does not ask questions. He asks for a coin.
An obol is a small coin once placed under the tongue of the dead. Without it, the soul could not cross the river. With it, the boatman would carry the soul to the far shore and into whatever waited.
In Obol & Ash, the act of minting is the act of placing the coin. The act of Crossing is the act of stepping onto the boat. The river is patient, but it is not kind. Some souls are received. Some are returned, with payment.
03 Summoning — the Ferryman's Rite
- Total supply
- 10,000 souls
- Standard
- ERC-721, fully on-chain
- Network
- Ethereum
- Reveal
- Instant. Full traits resolve at the moment of summoning.
There is no buy button
To summon, you answer the Ferryman. You speak to him, and he weighs you. He decides whether your soul crosses free or owes the boatman his coin. Most are carried for nothing; some are asked to pay. You do not choose, and you do not know — until he has decided.
The river is generous, but never the same twice. No one passage is promised free, and none is ever refused outright. What the Ferryman grants one soul he may withhold from the next. The only way to learn your fate is to stand before him.
04 The Six Forms
Every soul is born into one of six forms. Drop rates are weighted at mint. Mythic is permanently capped at 10 instances across the entire collection.
| Rank | Form | Latin | Mint drop rate | Hard cap |
|---|---|---|---|---|
| I | Wisp | Spiritvs | 60.00% | — |
| II | Coinbearer | Obolator | 25.00% | — |
| III | Skiffsoul | Navta | 10.00% | — |
| IV | Lanternward | Lanternarivs | 4.00% | — |
| V | Ember-Drowned | Aestvans | 0.90% | — |
| VI | Riverborn | Flvminis Natvs | 0.10% | 10 total |
Eight visual trait slots
Each soul carries eight independently rolled visual traits, with several variants reserved exclusively for higher tiers. The combinatorial space runs well into the tens of thousands of unique signatures per tier — no two souls roll the same seed.
- Hood Shape · 8 variants · Crowned unlocks at Legendary; Halo'd is Mythic-only
- Face Inside · 8 variants · Third Eye is Mythic-only
- Obol Position · 5 variants
- Coin Mark · 6 variants · Burning Brand is Legendary+ only
- Top Sigil · 6 variants · Lotus of Ash is Mythic-only

- Cloak Detail · 5 variants · Embered Legendary+, Ash Flow Mythic
05 The Crossing — Sacrifice
To raise a soul, you must give one. A Crossing burns a second soul as fuel to attempt evolving your main soul up one rank. The fuel is always consumed; the main soul is never burned.
Ascension
The main soul rises one rank and rerolls its traits within the higher rank's pool — same token, evolved. Its ascension count climbs by one.
Failure
The main soul stays exactly as it was — never lost. The fuel is gone, but the river sometimes remembers a debt, and on rare occasion repays it. Most often it stays silent.
The higher you climb, the harder the river runs
Raising a Wisp is almost certain. Raising a soul near the upper ranks grows perilous — the closer to Riverborn, the more often the Crossing fails and the fuel is spent for nothing. The river guards its highest forms jealously.
Mythic is terminal
Mythic souls cannot Cross — once a soul reaches Mythic, it is final. And only ten Mythics will ever exist; once the river has taken its ten, the highest Crossing seals shut, and the Legendary is preserved. The Crossing is a later rite — the boat does not open it at first light.
06 Etched Into the River Itself
A soul is not a picture stored somewhere far away. It is etched into the chain itself — every line, every ember, every mark of its rank lives inside the contract, summoned anew each time it is looked upon. There is nothing to take down, nothing to lose, no far server that can let the soul slip back into the dark.
The higher a soul climbs, the more the river marks it. The lowest wear plain cloth and a single coin. The risen carry embers that will not die. The Riverborn — the ten — are crowned in gold and fire, and the boat itself seems to hold its breath around them. What you summon is yours, eternal, and cannot be unmade.
07 Lifecycle of a Soul
- Approach — the collector answers the Ferryman.
- Verdict — the Ferryman decides: carried free, or asked for his coin.
- Summon — the soul is minted; its full form resolves instantly.
- Hold — the soul renders immediately; trade or keep at will.
- Crossing — a later rite: give one soul as fuel to raise another.
- Ascend or stand — the soul rises a rank, or stands unchanged.
- Mythic — if a soul reaches Mythic, the Crossing is closed. The soul is final.
08 Lore-Named On-Chain Events
Every meaningful action emits a named event on chain, so the entire lifetime of a soul can be reconstructed from the explorer alone.
| Event | When |
|---|---|
Summoned | A new soul is minted |
Sacrificed | A Crossing attempt: the fuel burns; the main ascends or stands |
09 The Pact
Every soul answers for its passage. Every Crossing is risked openly, in code. The rules are on-chain. The Ferryman does not lie.
You are not collecting. You are ferrying.
