Legend of Mir 2 - Official Public Crystal Source

Crystal is the most widely used open-source server and client engine for The Legend of Mir 2, developed and maintained by the LOMCN community. Originally created by Jamie and contributors, Crystal is a modern, fully managed C# implementation of the classic Mir 2 server architecture, designed to be stable, flexible, and easy to build upon.

The project faithfully recreates the gameplay systems of the original 1999 MMORPG by ActozSoft and Wemade Entertainment, while also introducing modern improvements such as:

🧰 Modular, readable C# codebase for both client and server

🗺️ Custom map editor and data tools

⚡ Performance improvements and bug fixes over legacy server files

🌍 Support for custom content, new features, and community expansions

Crystal has become the foundation for most private Legend of Mir 2 servers worldwide, serving as a cornerstone of the Mir development scene since its public release on LOMCN
