Languages you have to learn
Speak a tongue somebody never learned and they hear you through a wall — pitch and rhythm, no words. Learn part of it and part of it comes through.
What's in the world
Underneath the three ideas on the front page, this is what they turn into in play.
Strongboxes
Containers that stand in the world and belong to nobody. Whoever carries the key can open one — a thieves' cache, the watch's evidence locker, a merchant's lockup behind the counter.
What goes in is the item itself, not a note of what it was, so a strongbox can hold a debt, a payment or the evidence until somebody comes for it.
A key is not the only way in. Locks can be picked, and a key can be taken off whoever was trusted with it.
Carrying the fallen
Someone who has gone down does not have to lie there. Kneel over them, lift them onto your shoulder and walk them out — to a healer, to a bed, or somewhere out of sight.
No item and no spell is involved. Somebody picked you up and carried you, and everyone watching saw it happen.
The orc here reads as "Weary Orc" because his rescuer has never been told his name. Being carried does not introduce you.
Arrests that take time
Lawmen are appointed by name, wear their city's tabard, and carry a Writ of Accusation and a set of iron shackles. A shackled prisoner goes where they are led.
They can be searched on the spot — their pack gone through, their purse counted — and they will feel it happen.
Being arrested is a scene somebody plays with you. There is no respawn timer that ends it.
The interface comes with it
The launcher installs the realm's addons and keeps them current — the voice panel, the disguise, the boards, the strongboxes. You do not go looking for any of it.
A few comforts come along too: your bags in one window instead of five, and nameplates that stay readable in a crowded room.
All of it is installed into your own game folder, and the launcher says what it changed.
And the rest
Smaller systems, all built for a realm where nobody knows you.
Factions of your own
An organisation a character belongs to, with a ladder of ranks. The rank is what grants things, so a promotion is worth having.
Death you cannot walk off
You cannot run back to your own body and stand up again. It is the spirit healer, or waiting where you fell for somebody to raise you.
A look at somebody
Four short lines about the character in front of you: what they look like, what is wrong with them, how they carry themselves, one detail worth noticing. Short on purpose — the rest you find out in character.
An emote for the room
/do says what the world is doing rather than what you are doing, and carries no name. The fire, the rain, the noise from the street.
More than one thing tracked
The stock minimap tracks one kind of place at a time. Here mailboxes, bankers, repairs, trainers and vendors show together, and Find Herbs and Find Minerals stay on at once.
