Built Different

Every mechanic has been designed to reward mastery and make every encounter matter.

Skill Synergies

Related skills amplify each other. Anatomy and Healing push bandage heals beyond vanilla limits. Forensics, Tracking, and Carpentry reduce barding difficulty. Your skill choices compound.

Cooldown HUD

A live heads-up display tracks every active skill cooldown in real time. Provocation, peacemaking, discordance, healing, hiding, and more — always visible, always accurate.

Graveyard Encounters

Enter the Britain graveyard in Felucca and a Player Killer portals through to hunt you down. Portal VFX, voice lines, a 3-minute cooldown, and five minutes to escape or die.

7 PK Archetypes

Classic Dexxer, Pure Mage, Necro Mage, Ninja, Paladin, Archer, Sampire — each with distinct tactics, gear, and speech. No two encounters play the same.

Three Tiers of Danger

PKs come in Newbie, Advanced, and Expert tiers. Stats, skills, and equipment all scale up. Survival against a Newbie is an achievement. Surviving an Expert is a story.

World Atlas

Every new character starts with a blessed World Atlas. Open it to browse all towns, dungeons, and moongates, then click any entry to teleport there instantly — after a brief channelling delay.

Hunter System

Rare named creatures prowl Britannia across four tiers of danger. Hunt them for Hunter Tokens, redeemable at the Guildmaster NPC for exclusive rewards. Wanted PKs carry bounties too — kill them to claim their head.

Active Development

New systems ship regularly. Check the changelog to see what's implemented, what's being built, and what's planned. The shard grows with its players.

The NPC Hunters

Seven AI-controlled archetypes portal in to hunt you. Each has its own tactics, gear, and voice. None of them forgive mistakes.

"Step into the graveyard at dusk and you will feel it — a shimmer in the air, a sound like wind through a gate that isn't there. Then one of them walks through. It is not a player. It has no mercy. It has only purpose."

News & Updates

May 2026 Launch

Server is Live

AIther is officially open. The server is running on Hetzner hardware in Nuremberg. Connect now and be among the first players in the world. All custom systems are active — cooldown HUD, skill synergies, and graveyard encounters are all running.

May 2026 Feature

Graveyard PK Encounters Active

The Britain Graveyard in Felucca is now a dangerous place. Wander in and one of seven PK archetypes portals through to hunt you. Each has its own combat style, voice lines, and playstyle. Three tiers of difficulty based on your prowess.

May 2026 System

Skill Synergies & Cooldown HUD Shipped

All barding skills now benefit from the synergy system — Forensics, Tracking, and Carpentry reduce difficulty on Provocation, Peacemaking, and Discordance. Anatomy + Healing boosts bandage heal output. The cooldown HUD tracks all of it live on screen.

May 2026 Feature

Hunter System — Bounties & Rare Targets

The Hunter System is live. Four tiers of rare named creatures now roam Britannia, each worth Hunter Tokens when slain. Turn them in at the Guildmaster NPC in Britain, Trinsic, or Minoc for exclusive rewards. Wanted PKs have been added to the track — kill a Cutthroat, Murderer, or Dread Lord and claim their severed head as proof.

May 2026 Feature

World Atlas Added to Starting Backpack

Every new character now begins their journey with a blessed World Atlas. Open it to see all towns, dungeons, and moongates across Britannia. Click any entry to teleport directly there — no rune libraries, no gates. A short channelling delay applies, and the cooldown HUD counts it down.

May 2026 System

Encounter System Expanded to 40+ Zones

PK encounters are no longer limited to the Britain Graveyard. The encounter system now covers over 40 named zones across Felucca, Ilshenar, Malas, Tokuno, and TerMur — dungeon levels, entrance corridors, and deep boss floors all have their own encounter tables. Tier scales with zone depth. A 30-minute per-player cooldown prevents farming.

May 2026 System

Orb & Currency System Introduced

Twelve types of Orbs now drop from monsters across the world, each tied to a damage school or character attribute. Essence Shards bind to your character and represent progression. Scroll items grant temporary boosts. The full economy layer — how Orbs feed into crafting and advancement — is still being designed, but the items and drop tables are already active.

Coming Soon Planned

A Living World — AI Guild Factions

The next major phase of development is underway. Twelve AI-controlled guilds will inhabit Britannia — blue, grey, and red — each with 12 members who follow daily schedules, hunt, bank, chat, and fight. Your reputation with each guild shapes what quests you receive, what prices you pay, and whether their members are friendly or hostile on sight.
