Poor Celia, she picked shitty friends.
Kashell, Aelia, Grey and Lemia were all good people (although Kashell was stupid and Grey never saw her as a lover because of Lemia)
The main problem with her friends is that they were ready to sacrifice themselves for a cause while she wasn't.
It's interesting that you'd pity the one that lives over those who died.
A good in-game quote for this would be:
The death of a loved one. For they that remain, the wounds grow deeper and deeper... They that remain grow weaker and weaker, an agony incomparable, their hearts in bondage.
Can you not see it? She has ceased to live, frozen in time. It is the same as if you had slain her with one of your arrows.
and damn you Dice... I need to find the time for another playthrough of VP...
