To fill up my PL, I'll claim the following:
* Kiken No Toge (Treacherous Pass) PL 1 : IR 0
And add the following artifact from the Rokugan book:
Katana of Fire - The katana of fire is a +3 flaming katana with the speed enchantment. In addition, twice per day, the wielder may spend a Void point to cast fireball as if he were a wizard of equal or of 3rd level, whichever is higher.
I would propose a +4/+2 character bonus for this item. Having been lost since the Day of Thunder, it is now wielded by Shiba Temuro.
