Tempora Heroica is run by the old implementers which ran
and made archipelago. Many new zones have been added to the original which
offers the players to explore and tones of new codes have tried to improve
the mud making it more playable. I've heard that a new code and fighting
system is being coded atm and should make the mud a lot better. More news on
this when it is officially opened.
Coven is not really open yet but it looks like a great mud.
A few new codes such as clan and house codes have been made and a new combat
system is in progress. Only a handful of zones are available and builders
are wanted to help to build this great looking mud up.
