I dig it! My Vulp has some odd stuff going on with the void but is a shaman, I’ve added it as a plot hook but haven’t done much with it yet. I like the idea of “tripping into the Void.”
While I’m a pretty casual WoW player, I could see some herbalism around void-touched plants, especially the kinds that have hallucinogenic effects - maybe something he accidentally stumbled upon that he now actively seeks out? I’ll phone a friend and see if they have ideas. Alchemy might need to be involved to make the right mixture.
If you’re looking for plot oriented, the guild I’m in does have a lot of that and they’re always looking for new character content, both in Discord or in WoW. I’ve found it’s a lot easier to schedule it out that way too.
