Ice and Fire: Dragons in a whole new light!

"For hundreds of years, Dragons have roamed the lands of the Known World. They are not simply pests and menaces, but the main cause of the loss of many lives. Only a brave few can slay a dragon. Even less can tame one.

Welcome, to Ice and Fire.

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."

Create

"Welcome to Create, a mod offering a variety of tools and blocks for Building, Decoration and Aesthetic Automation.

The added elements of tech are designed to leave as many design choices to the player as possible, where item processing doesn't happen inside a single block with funny textures, it requires a set of actors working together in many possible arrangements.

Check out the wiki and in-game Tool-tips for further info on how to use these features, and stay tuned for an ever-growing selection of possibilities for Creative and Survival Minecraft."

Enigmatic Legacy

"This mod is designed to provide tools that will aid you in exploring seemingly endless reaches of Minecraft's worlds. As well as new resources, powerful gear and ancient relics - to reward you for doing so. Despite revolving around themes of arcane and mystery, Enigmatic Legacy doesn't stray too far away from what vanilla has to offer, instead attempting to expand upon it's mechanics and fill in the holes left open.

That includes, but is not limited to new tools, armor and weapons, dungeon loot, potions, enchantment manipulations, means of inventory management, means of making chunk-sized holes in your world, means of management and new applications to ethereal substance known as experience, 1000th implementation of item magnets, faster and more convenient ways of villager enslavement, and, of course, god-tier gear somewhere around the corners of the endgame. By the power of Curios API, there also are a lot of accessories, both classical ones like rings and charms, and completely unique types - like scrolls and spellstones."
