Odyssey.

Lost in a world not unlike your own, with nothing but a blank atlas and a backpack, there is no way back to your own world in sight, but will that stop you from looking?

Odyssey is a modpack that is inspired by RLCraft (Try it here if you've never played it ;>), centered around exploration, ambience, and semi realism (note that the semi-realism does sharply increase the difficulty, especially in the early game, so be prepared.).

Some of the key features include:

Realism

• Thirst bar & temperature (Tough as Nails)
• An overhaul of the health system (First Aid)
• Dynamic trees (Dynamic Trees)
• An overhaul of early-game progression (No Tree Punching)
• Seasons (Serene Seasons)

Exploration

• A really cool map (Antique Atlas)
• Portable Sleeping (Comforts)
• Respawning near death location (Better Respawn)
• Backpacks for the sake of portable storage when exploring (Sophisticated Backpacks)
• Ships (Small Ships)
• Effectively a fast travel system (Waystones)

Ambience

• A bunch of new biomes (Biomes O' Plenty
• Lots of new fish (Aquaculture 2)
• Passive birds (Exotic Birds)

Misc.

• A way to increase max health by trying new foods (Spice of Life: Carrot Edition)
• A lot of new foods to go with the previous entry (Pam's HarvestCraft 2 - Food Core)
• A way to have your base be a thriving town that does stuff while you're out exploring (MineColonies)
• A bunch of other stuff (Check the mod list)
