If you don’t have too many members, it’s probably easier to join an active guild. We have some spaces in #58 TUF: Power Gems. While not Zombies, our origin story is about Liches using power gems to control a wraith army to fight goblin hordes. So we’re fellow undead.
We’re part of The Unholy Family so across our 4 active guilds (and our vacation guild) we surely have some spots.
