Middlehaven is a mythical realm, one of five kingdoms in this completely original world setting.
Unfortunately, Middlehaven's step-system of levelling up and purchasing attributes, as well as it's combat system, was rendered obsolete when Dungeons and Dragons 3.5 came out and Conrad declared that WotC had "fixed" all of the problems that had caused him to spawn the Middlehaven system in the first place.
Enthusiastic Middlehaven players await the release of Middlehaven LARP, which Conrad is now working on.
MIDDLEHAVEN LARP IS UP AND RUNNING!!! MiddleHaven Egroups
