I got to agree with Polo on this one.
While my character would naturally love to see the end of Grief and her Corruption, such a thing is impractical and impossible both in OOC and IC.
IC:
Grief would simply be too powerful. Altera has enough fighters and such to hold her back while we make our escape (To the Exodus), and possibly harm her a little; but even from within her prison she is able to cause devastating damage to us, imagine what she could do outside of her prison!
Simply put, She is too powerful to defeat... permanently.
OOC:
It will destroy the server. For starters, we need Grief so that we can initiate an Exodus. I can't think of any other reason why we would go to a new world... and before you say anything, we need new worlds occasionally because the old ones get cluttered with ghost-towns. The Exodus gives us a chance to remove them and give us a change of scenery.
Also for OOC, the server would get unbearably boring if we had no Grief, as it means everything would more-or-less be peaceful. Things get boring quickly if there is long-lasting peace and people would start leaving the server because of it.
