The Dark Forest[edit]
After recovering the Sword of the 2nd element, visit all the towns and talk to all the people. They will direct you to Gran, north of Granville. In Gran, people say that the sword of fire is in the dark forest, to the north of the village.
There are two special locations in that area: a purple crystal in the forest and the "Fire of the Serpents" beyond it. If you check the map (faerie spell, e.g. 
), you will see that the purple crystal conceals a treasure.
Once you figure out how to liberate the contents of the crystal, you must locate the "Fire of the Serpents" to charge what you have found. The Fire of Serpents is a stream of fire which emanates from the ground. It is located to the north west of where you found the sword. Bring it there to revitalize the item.
You cannot simply take the contents of the purple crystal under normal circumstances. But you must find a way to obtain it in order to proceed. It just so happens that Fairy magic is the key, but not any of its informative spells. Instead you are meant to cast an attack spell using a single fairy rune such as 
or . Attack the crystal and the contents within, the Sword of Fire, will be yours to collect.
The sword of the third element[edit]
Bring the charged sword of element to the wizard in Gran. In the case where you started the game with fire magic, the sword of fire will stay in your inventory.
Fire magic has offensive spells only, but they are rather potent. See Magic for more information. Always remember that attack spells use up health points when you cast them, so be sure that doing so is actually more advantageous to you than a straight physical attack.
