Old School Megadungeon Campaign For Dungeons and Dragons

Hi, I am a DM who is kicking off a new old school megadungeon campaign set in the World of Greyhawk. The campaign will be the exploration of a megadungeon called the Ruins of the Undercity and will include more that one player character party exploring the ruins at the same time - and possibly coming into alliance or conflict with the other player character parties .If you are interested in playing, reach out to me and I can give more information about the campaign.
