Swamp

Content Expansion 1 is activated on EU #1. It is a guarded content layer over unchanged Worldgen V4, not another biome or generator profile.

See Resources by Biome for the content-layer sources.

EU #1 uses Worldgen V4. Its environments are Plains, Forest, Desert, Swamp, River, Sea, Ocean and Caves. Terrain, water depth and resource placement follow the authoritative server generator.

Water regions: Rivers stay inland and meet the coast. Below sea level, Sea or Ocean takes precedence, including swimming depth and fishing catches. Rivers do not form freshwater corridors across open marine water.

Moist grassland with scattered trees, swamp grass, occasional mushrooms and shoreline reeds.

Terrain and presentation

ground: #4f7f43

Base colors come from the game renderer. Gentle, stable tile noise adds shade variation without flicker. Plains keeps fewer trees and more open, flowery space; Forest keeps its denser tree cover.

Resources and travel

Gather the natural resources present on each tile. Trees yield common Wood and Pine cone under their normal mining rules. Plant a cone on clear, suitable dry ground to grow another tree.

Wildlife and threats

• Chicken
• Cow
• Marsh Leech — actual water tiles only
• Marsh Turtle
• Mire Toad
• Pig
• Sheep

Ordinary chickens, pigs, cows and sheep are very rare: their natural spawning uses a 12% seeded chunk eligibility threshold within the existing local budget. The seed fixes which candidate chunks are eligible, so repeated spawn ticks cannot refill every chunk with ordinary wildlife. This is a habitat eligibility rule, not a guaranteed population percentage; animals may also walk across chunk and biome boundaries. Wolves do not naturally spawn here. Mire Toads keep their normal swamp encounters.

Species share the existing local encounter budget. Listed habitats do not guarantee a spawn. Read attack warnings, wolf packs and poison.
