Why EterSystem

Built for those who run campaigns, not spreadsheet vendors.

Forget shared spreadsheets, PDF sheets full of scribbles and GMs jotting HP on the back of a notebook. EterSystem brings sheets, NPCs, formulas and rolls into one place — with the visual weight a great RPG deserves.

  • 01
    One portal per player
    Each player gets a password. They open the portal, enter the password and see their full sheet. No sign-up, no installation.
  • 02
    Browser rolls
    Every attribute, skill and ability has a die ready to roll right next to it.
  • 03
    Separated by campaign
    Each RPG is an island: its own archetypes, abilities and skills, completely isolated.

How it works

Three steps from the table to the browser

I

The GM builds the world

Configure the system, define archetypes, abilities and skills for the campaign. Your table's rules, your formulas.

II

Characters come to life

Create full sheets for players and NPCs — attributes, lore, labels, attacks. Everything in one place.

III

Players enter

Send the password to the player. They open the portal on mobile or browser, type the password and land right on their sheet.

What's included

An arsenal for those who run stories

Every tool was designed to fit the table — without getting in the way of the narrative.

Password access

The GM sets a password per player. They open the portal, enter the password and immediately see attributes, vitals, abilities and attacks. No sign-up, no installation.

Customizable damage formulas

Expressions with aliases, modifiers and conditionals. Your table sets the rules, the system executes them.

Multi-campaign

Multiple isolated RPGs

Each campaign is a closed universe — its own archetypes, skills and abilities, independent teams.

GM's NPCs

Full sheets for NPCs

No loose papers. NPCs carry the same level of detail as player sheets, with GM shortcuts.

Base roll

A d20 always at hand

Fire a direct roll with the RPG's standard die. Result at the table, history in the portal.
