AthenaX (Server Emulator)
From RO Wiki
AthenaX was the name of an offshoot of the original I-Athena emulator which was released exclusively in Japanese. It was relatively short-lived, releasing 5 versions (AthenaX_01 to AthenaX_04, and AthenaX_004_justforfun01) which sadly were not archived. It appears the developer was working on the project for personal reasons, adding a few features and bugfixes to I-Athena before eventually abandoning the project in favour of their own blog software.
