This modpack adds lots of Avatar related things to Minecraft. It's really good to play with friends and it was originally created for a server. It's based off of ButterJaffa's Avatar series, which you should go check out. I added different mods to make it more interesting. I do not own any of the mods in this modpack. Anyways, I hope you have a great time exploring the world of Avatar! :D
(And, yes, I did copy and paste that from the original modpack description because I'm lazy :/ )
