Hey I never heard about voidpunk, can you maybe explain a little bit what that means to you?
Besides that I think you can start a community here any time as long as it fits within the server rules. I hope you try that out. :D
In the fediverse it sometimes heavily matters because small communities dont get discovered by user of other instances/servers easily.
For your specific question I would encourage you to also (cross)post it to !meta to reach most of the users on this instance/server. I think just leaving it here, your question might not get seen by many.
There are also big communities like !newcommunities@lemmy.world which might help you find others interested in voidpunk.
