The Lost Explorer (An Atlantis Fanfiction)

We all remember the climax in the Atlantis story, a spur of the moment attack, against highly skilled mercenaries. That somehow managed to work... Does anyone remember what turned the tide in the Atlantians favor?
That key point was the woman Lieutenant Helga Katrina Sinclair, we all know what happend to her...Or do we?
What if she survived the eruption? Healed from her injuries, and now left in Atlantis by those thinking her dead along with the rest of the near murderers.
Its time to see what really happened after the team left for the surface, can those who have already been branded ever change?
