Soulless on the Sword Coast

Well... how do I even start. I'd say the day started off well, we met a fellow elf (drow but I won't hold that against her, I kinda always liked them) adventurer named Xoeamarra. She seems sufficiently pleasant and I think Kanny vouches for her, which was good enough for me. I do love her crazy accent and turns out, she's pretty damned good in a fight. Without question, meeting her has been the high point so far. I feel terrible that we immediately led her into such a complete and utter shit show.
 
Surprising pretty much no one, Gallio Elibro proved to be an unrepentant asshole until the very end. Burying all of our distrust and ill will, we decided to help him try to control these extra-planar monstrosities he was conjuring. He couldn't leave the god damned beacon alone and now, of course, he was in over his head... Or that's what we naively thought...ugh...it's times like this when I'd trade all my young brains for just a pinch of sagacity. How the hell would we even GUESS that conniving cockroach actually just wanted us to fight off those monsters so he could take a shot at the Ruinstone; the same one that killed Thalivar and destroyed this town once already.
 
The fight was, in fact, tough but everyone played their part to down those aliens. Constantly flipping back and forth between the Material and Ethereal planes was definitely a first for me but we managed ok. Then we found the son of a bitch...unconscious at the foot of the Ruinstone! Even more shockingly, we saw THEM; the Swords of Leilon themselves! Well, two of them at least; Augusta Krul and Ogri Ninebeards (I didn't ask them what happened to the 3rd, which we should probably before we leave)... this explains why we saw Augusta that one day on the perimeter of the Tower.
 
After pleasantries, they went on to tell us the story of why (and how) they were still there and shared some of the secrets of the Ruinstone. Unbelievable and horrible secrets along with credible information that Ularan, Ebonbeath and potentially others now know of its existence and will be actively searching for it. The stone could make Ularan & Ebondeath unstoppable and I knew I had to do everything possible to ensure that did not happen. They CANNOT under ANY CIRCUMSTANCES win; it could mean the end of the Sword Coast, our families, us, everything. I couldn't fathom my family and our friends subjugated, OR WORSE, by that demented necromancer. Though I have a good 900+ years left to go, I did the, heretofore, unfathomable. With family, friends and this motley crew in my thoughts and tears leaking out of my eyes I bound my young soul to that cursed gem. I have never been so terrified. I didn't think I had it in me, I don't think anyone has ever thought I had it in me...but there didn't seem to be another way out. Hopefully Augusta and Ogri can keep it safe long enough for us to get to Ularan... but if either of us fail, no one will remember I was ever here.
 
p.s. I also can't die. No way, no how. I must find more ways to protect myself. Study has kept me alive so far....hopefully study can take me the rest of the way.
p.p.s Turns out Gallio was nowhere near as powerful as I thoguht, I should have taken my shot when I had the chance. Maybe I wouldn't be in this impossible predicament if I did!
