Referring to the captain of the newbie school future dimension. While we can't GIVE you his name, we can assure you that it is somewhere in the descriptions in the future dimension of mud school. Look at everything in the rooms - any noun has the ability to let you know what his name is. If you look around you will find it.
Remember, don't tell anyone this information as it is 'quest knowledge'.

4 Dimensions is a text based mud so there are no pictures - no graphics. By reading the description of the room, you get an idea of what the room is like and if there are any exits. 4 Dimensions gives players the choice of running around and killing things - hack-n-slash-, doing quests or a combination of both. Doing quests gives you a chance of getting the better equipment out there because it takes time and brainpower to do.
