A list of mods that turns Minecraft into a Multiplayer RPG. 
-Ice and Fire: Dragons
Ice and Fire is a mod created by both Raptorfarian and Alexthe666, which hopes to add dragons in a proper way. Currently, Dragons have two types: Ice and Fire. Fire Dragons breathe fire and roam most of the habitable world, whilst Ice Dragons inhabit the coldest places known to man and freeze their prey to death. Both kinds of dragons spawn naturally as adults. And news has reached us of a new discovery: Lightning dragons, powerful nocturnal creatures that deal blasting bolts of lighting to kill their prey.
