Allright- I'll bite. I mean, we haven't had much of a SCoP whinefest this year afterall, so about time someone started
For further reference - EW is the Worshipper of the Elementals layman guild and SCoP is the Spirit Circle of Psuchae occupational/caster guild.
As for SCoP and alignment. Kas and Amberlee you are both wrong/right.

SCoP is goodaligned, and while not so directly anti-evil as say a knight or ranger that is their placement in the alignment spectrum. Yet at the same time they have been very neutral on many accounts.
I do not want to spoil the joining process for anyone who might be interested, so all I will say yes if you only follow the elemental alignment/morality spectrum of EW (a separate guild!) the SCoP should perhaps have been neutral. But "there's more than meets the eye!". SCoP has ties with Calia beyond just the Elemental gods, as does the EW.
As for why the SC was not created as a direct occ neutral branch of the layman guild.
There are 3 main reasons:
1. Initially the idea was a branch for each of the elements in the EW (bringing back the Walker project from 98/99). Bishop was at the time coding a occ neutral mage caster guild in Calia not connected with the gods, but only with the elements of fire/water/cleric - a Cleric one would have been redundant. That left the spirit element the only element not covered in Calia at the time.
2. Jaacar was not allowed to create a neutral occ caster, for the reasons of the evils already having 2 casters.
3. The SC and EW both has alot more background than just "follow the Gods! and their alignment" - they already did over a decade ago Kas.
Calia is one of those domains, where you do not get things spelled out for you. There is the obvious - what you can see and read directly. Then there is the underlying theme which takes some investigation.
However, Amberlee, it is true the SC has not been part of the Alliance and has tried to stay neutral in most of the conflicts the Alliance had. I will try some up some of the main reasons:
1. When your guild constantly has a declaration of war from the Mages and the Vampires (either/and) you have your hands full already

2. No fighter guilds (the Alliance) wants anyone in their midst (SCoP) who is currently fighting one of those two guilds (MM and Vamps) - understandably. It is not that the Alliance and SCoP didn't try. It simply was not meant to be

3. Therefore the SCoP has decided a more neutral and withdrawn stand - one of the great things about having a complex RP background and different philosophies to pick from.
In addendum on alignment and picking side - a few funny facts (Well they are funny to me

):
Did you know the SC and Neidar were almost at war once? It was one offence/attack from a full-scale..(SCoP is was certainly ready to leave behind their goodie & neutral stance then).
Did you know the SC was at a point allied in effect with the PoT and DA hunting evils? .. (Was SCoP being good or neutral, was the PoT/DA good / neutral or were everyone just opportunistic and selfish - evil?)
Alignment is not always about sides in Genesis and thank you for that. I like the alignment spectrum as guidelines in a fantasy setting, very much, but by my accounts it should supersede everything.
As for the Elementals and undeads. You are all wrong and Aimee is almost correct
The Worshipper layman guild was created on the code and premise of the smoldering ruins of the old Hellfire club I was told. Ever since its creation (93/94?) has it been anti-undead. Undeads cannot join and the Undeads are "not so street" by all the Elemental Gods. Nothing new there:)
It is true that it is not an active part of the Worshipper guild to be anti-undead as in hunting them and directly opposing them. I will leave it for you all to speculate why. Angmar and DA have been and are welcome into EW, regardless of their service to other Gods. I again refer to the underlying history of the guild.
With the playtest of the Firewalkers and Windwalkers (occ branches of the EW - not a separate guild like SCoP) back in 98/99, Psuchae had revealed itself around 96/97, and it is possible that the spirit walker branch was meant to be anti-undead then as well. Perhaps from a neutral aligned stance, but with the Mystics still not entirely closed at the time - the emphasis would probably not have been so strong as the SCoP. Unless Jaacar comes back - we'll never know
My dream scenario the caster and alignment spectrum?

have the Mystics come back or the Keepers of Telberin open (Holy aligned Cleric guild that was getting ready for playtest in 99/01ish) and either one of those guilds fill the slot as the active caster guild of the Alliance.

have the WoHS come back and fill the slot of the scholar mage - with room for any one alignment

have the EW and SC merge into a neutral / neutral good withdrawn Cleric guild

have the Khiraa come back and fill the slot of the utter alien evil guild

have Gorboth finish his Chemosh guild to add even more to the spice of it all

have a huge heap of new and old players fill these guilds
Just my cents on all of this...
