Spoilers below:

ok, Londa is the woman in Cutlass inn in Luskan who wants you to get her kids back from one of the High captains. I completed the quest, and turned it in. Upon leaving as many of you already knows, she dies. I spent quite a few times reloading to try and save her to see what if anything would happen. I manage to save her by using stone of recall, and walking back to her. I was then closer to the baddies when they spawned in. I saved after foes would die, so long as it seemed I had the agro, and would reload if things didn't go well and she died. Anyway, after several reloads I managed to save her lol. I got better loot than I did the previous many times I killed the baddies. Each dropped 99 fire arrows, so worth doing it you archers :) Unless I just got lucky. Londa doesn't say anything different. Still, PLease let me go. The devs intended her to die, which is what I expected, but wanted to make sure. the fire arrows is nice. I use a bow as my second weapon.

Congratulations :). I remember trying to save her myself and failing terribly. Using the stone of recall to approach from the other side is a neat trick.

My thief set several deadly traps near the enemies spawn point then I saved and turned in the quest they were nearly all dead by the time Londra got to them, and my speedy maniacal liitle dwarf buddy took care of the rest, firat try :)
