(+3 EXP) Walking Horror House: Spending years in the Traslag is bound to earn anyone a number of of unwelcome body invaders, and as Vialesa had spent ten, she became the unfortunate home of countless creatures. Though she appears normal on the outside, Vialesa suffers from internal injuries from time to time as the horrors move about inside or feed on her flesh Every day Vialesa must make a Hardiness (DL 20) Roll or suffer a -1 Endurance Penalty and a -2 to all Rolls for the day. A Fumble decreases her Endurance by 2 and the penalty is -5. Also this horrible affliction has done some permanent bodily harm. -1 to Vitality. 

(Took out the spawns a horror thing. Just gonna go with flesh eating parasites. Your chara should really work on getting that cured. Luckily we have a botanist in the group). 

(+? EXP) The Woods Linger on All: Every day, Vialesa must resist the effects of Traslag's sinister aura or risk falling unconscious and awaking in their woods mysteriously. 

This Flaw confuses me. So she teleports back to the woods? That seems... well, its freaking impossible actually, so that is a no...

Also her blade, while I do accept it, she is not physically strong enough to wield it. She would need at least a Might of 5 to wield the equivalent of a Bastard Sword (as Katanas are usually considered as such). She can still wield it, but for every point of Might she is below the required amount she suffers a -2 penalty to Melee when wielding said blade. 

Checking the handy dandy map on the first page, we will say the Traslag is in southwestern Ithelia (cause there would be a reason why that place wouldn't be in Gallastre). And yea the... er... monster thing could be one of the many dark creatures that roam Ithelia (or in this case makes those woods its home). There are probably things out there more powerful and horrifying though (trust me ;3), but yea, everything checks out except that second flaw of yours and the fact that your chara is too wimpy to hold up her weapon. It can be a different kind of lighter weapon if you want, but still, recommend that you boost your might a smidge anyway if you are gonna be a Melee fighter since Might helps with bonus damage to melee weapons.
