Aden Chronicles

Migrated a decade-old L2 server to a clean, documented backend the operator's own team now maintains confidently.

100%

protocol parity

10x

faster onboarding

vendor lock-in

Overview

Aden Chronicles ran on a heavily-patched L2J fork with no documentation and a shrinking pool of people who understood it.

The challenge

Any change was a gamble, onboarding new engineers took months, and the risk of a fatal bug grew with every patch and geodata change.

Our approach

Captured protocol and gameplay behavior in a parity test harness.
Incrementally replaced subsystems behind those parity tests.
Documented architecture, data flows, and operational runbooks.
Ran pairing sessions to transfer ownership to the in-house team.

The results

Aden Chronicles now runs on a modern, documented backend. New-engineer onboarding dropped from months to days, and the in-house team ships independently.
