This mod aims to bring back, and give life to a lot of scrapped, unused, and even concepted content and features from The Aether's past. This gives even things that never made it out of the idea stage a chance. This includes content from Aether I, and even Aether Legacy itself. Any content that did not have any special ability or purpose will be given one, example being the Aerwhale King, which only existed as a name.While the mod does not aim to implement much Aether II Genesis/Mutation era content, there are exceptions. Features currently included from that era are purely visual, and were able to be slotted in as-is.
⚠️ Disclaimer
This mod may be missing some lost content, as either we had no idea on what it could've been, or we didn't get to it. Some content included may be unfinished, or may even be changed. Some included content may not fully/accurately represent what it may have been. However we have done our best to make the content as fleshed out as possible.❓ What does everything do exactly?
If you need to figure out what something does, the Book of Lore will give you any details you need! If it says it doesn't do anything special yet, then it will have it's ability added in the future.
New Dungeon: Platinum Dungeon
The platinum dungeon was concepted to be the fourth dungeon to finalize the mod! We took that idea and design the dungeon and boss fight as the Aerwhale King!Other Additions

Gale Stone A cool, blue stone that makes up most of the Platinum Dungeon's structure. It cannot be destroyed until the Aerwhale King is defeated.
Light Gale Stone The glowing version of Gale Stone. It can be found in the Platinum Dungeon along with Gale Stone. Likewise, it cannot be collected until the boss is defeated.
Songstone The sound this legendary stone makes can only be heard fully by the Aerwhale King. The sound keeps his mind in a tranquil state. If activated, he will prepare for battle.
Power Gloves These gloves increase force behind the wearers punches. When using them to punch, they knock enemies much farther back than usual.
Platinum Key A super shiny key awarded by the Aerwhale King after being defeated. You can use it to claim the treasure on the second floor of the dungeon!
Invisibility Gem A stone that has a chance to allow the wearer dodge a blow, concealing them, possibly helping them to escape a rough situation.
Phoenix Pickaxe The metal of this pickaxe is molten hot, it melts through stone, allowing the smelting of ores instantly.
Phoenix Sword A heavy, molten sword which burns its foes to a crisp. It almost hurts to touch! Using this on animals can make them drop cooked meat!
