Aura is an open-source server emulator for the MMORPG Ma***ogi. It was in public development and available via this forum until January 2017, when Nexon kindly informed us via a DMCA that they didn't like us creating a server emulator for their game. Today, Aura is still in development, but unfortunately it's not available to the general public anymore. That being said, Nexon is not very good at sending DMCAs, and they actually left every single fork and mirror out there alone, so if you wanted to, you could easily find the last version that we published back then. Google is your friend.
This sub-forum serves as a kind of "legacy support forum." If you get your hands on Aura, feel free to discuss it or ask questions here.
