I'm currently running multiple versions of a "Dragon Heist"/"Dungeon of the Mad Mage" campaign as well as multiple versions of a campaign containing all of the adventures in "Tales from the Yawning Portal." I also have a campaign using the "Tomb of Annihilation" and "Vecna: Eve of Ruin adventures," as well as a couple of campaigns that take place in my homebrewed world of Paryllaxx. All campaigns are designed to take a character from 1st level all the way to 20th; players are also welcome to join a campaign already in progress, at which point their character will start at the same level as the rest of the group.
