It is strange that especially Windemere and Amorana whose brother was slaughtered and left the game are opposing you.
It is strange that especially Windemere and Amorana whose Elemental patron confronts the Undead and left the game are opposing you.
It is strange that especially Windemere and Amorana whom I would expect to support you most are opposing you.
I am sure the CHARACTERS Windemere and Amorana supports the effort of slaying all undeads but there is a difference between that and anything happening on this Forum or OOC. Your character can hate a guild while you as a player still want that guild to exist and flourish.
When I started playing Genesis the mages were the most feard people around, I got nervous for just being in the same room. One time, a long time ago, a mage casted some kind of fear spell on me to make me go away for burping. I think he said I polluted the air or something. And that just added to the excitement of the game. He didn't attack me or insult me he just wanted me to go away. I missed that boat but that didn't matter because I remember scrolling up to see what had happened several times.
I knew nothing about the abilities of the mages back then more then rumours about something called "statcloud" that made you into a newbie or the dreaded "blackbreath" which would kill you. And those tiny hints towards their spells made me fear them. But it didn't keep me from fighting the orcs in Ithilien, it made it better. I ran at the sight of any mage there. So I was not a fan of them to make it short but without them it wouldn't have been as fun to sneak into Ithilien to fight orcs.
I am not a fan of the mages now but I think they have a important part in the game. Maybe something like the evil "puppetmaster" that pulls the strings of the bloodthirsty hoards of Angmar and mystery and fear are big parts of that role. The Circle needs a powerful enemy to be able to reach its rp potential.
So even if Windemere and Amorana argues against this it is their players and not their characters that do it.
