Riron, did u try Discord link in my message below yours ? it will take u to a Discord welcome/make an account page... U will need a name/ password... it should take u to the "official" Obie Discord server, (Tyrfalgar = Aethon GM). scroll down the list of pages in left column to ' Tech Support '... everything you need for Macs thru 10.13 will b pinned there... also for Winblows machine. if u do not find what u need leave a message in 'Tech support'... mayb in 'General', where most chatter is.
anyone wanting to join Oberin, try this Discord server https://discord.gg/hSk9GGM that link should get you to "official" Oberin channel Tech support... DLs you need to install / run Obie on new Macs 'n Windows machine are pinned there... that is also where to ask for Help.
A buddy and I got into a bit of a lookup frenzy trying to find the date of when Oberin was first online and playable to the public. Earliest date we found was 2001 but that isn't Oberin way older? I remember it working on an OS 8 machine.
Edit 2: Peeking through the early part of the traxus forums, you will find some mentions of there being a yahoo group. Even in 2001, people were lamenting the loss of this group and all of the insight it provided into the early world of Oberin. The link to said group was groups.yahoo.com/oberin/ – it is not on the Wayback.
