Furnace

are NaN Objects in.

Location and Uses
NaN Furnaces are found outside the BotW: and the BotW:. They can be lit with a BotW:, which will then power the NaN Guidance Stones inside of the labs. At the beginning of the game, both NaN Furnaces will be unlit.

When BotW: arrives at the BotW:, BotW: will notice that his BotW: is missing its basic NaN Runes. BotW: offers to restore them, but only if BotW: lights the BotW: outside and activates the lab's BotW:. Once BotW: does this, the BotW: for the BotW: will be activated. Inside, BotW: points out that the BotW: is reacting to the BotW:.

At the BotW:, BotW: offers to provide BotW: BotW:, which is made by the BotW:. However, since the BotW: outside is unlit, the BotW: needs to be retrieved from BotW:. When BotW: successfully lights the BotW:, the BotW: outside of the lab will be activated. BotW: shares his excitement that the BotW: is working once again, believing it was due to the power of his love. BotW: then informs him that he lit the BotW:, which BotW: thanks him for.
