Worldsinger

Lumar is a dimension of its own, with its own blocks, biomes, weather patterns and an archipelago where oceans are made of alien spores rather than water. The mod introduces six aether spores, each with its own mechanics and behaviors, and spores react to contact with water blocks, snowballs, eyes and living entities, including players. Spore crafting and brewing systems let players experiment with them, and the release adds 79 new blocks and 49 new items.

Vent blocks in the spore oceans can be removed to turn spores solid, and vents freeze time, creating random stillings and temporary deserts while an ocean turns. Players are warned that kicking up too many spore particles is dangerous. Ribbons of water known as rainlines roam the world along predictable routes, except in the Crimson area, and a Sea tracked map follows them.
