"I am probably just inept at version control and accidentally deleted everything."
-Cham after accidentally killing this promising project
This was going to have Legend of Zelda style gameplay, where the end-game was to make the ultimate sword, and progression occurring when you forge new equipment with materials taken from "temples."
The plot focuses on the inhuman player-character, who travels to a desolate island to create a weapon worthy of a hero.
The protagonist's very body is evolved to do little else than metallurgy, and views smithing as sacred; it's quest is akin to a holy pilgrimage or a rite of passage.
