I'm the friend, and I'd possibly be interested in playing a Warforged Artificer-or-Druid, depending.

Did I miss any errata? I tought there were NO GODS in Sigil, and clerics couldnt get spells. What would be the point of playing a cleric?
I'm a Planescape scholar, kinda. I may be wrong, but what I can gather is that there are no gods allowed in Sigil due to the Lady of Pain. However, this is not the same as clerics and spells -- clerics are still granted spells and so on, but gods themselves cannot physically enter.
Unless you are Vecna, apparently. But.
Temples are fine, also. There's a Temple to Hermes in the Lady's Ward (cf.
In the Cage: A Guide to Sigil). Generally, the Lady is not concerned with the workings of deities per se, except insofar as they threaten her or her city -- thus why gods aren't allowed to enter. Veneration of Aoskar, God of Portals (deceased), is also prohibited for obvious reasons.
Also, Taitzu52 is right, I believe -- no transportation dweomers work in Sigil. This means Summoning and Calling spells, Dimension Door, Teleport, etc. This rigs it so that the only way in and out of Sigil is through the portals, which are of course controlled by the Lady of Pain.
(Hmm. Lady of Pain and Lord of Blades...)
