Official Discord

They are working on it.

It's mentioned in the FAQ that they will publicly announce when they do - at full release.

there is one with a few hundred people... but it feels more like a circlejerk between a few people who wont let anybody into their conversations and ignore everybody else. feels like its a discord for 5 people with a few hundred audience. pretty obnoxious. i dont use it much

If you're looking for some major SoulWorker discord servers at the moment, I would recommend SoulWorker HQ and Burning SoulWorker.
