Your not immune to Locate Creature and eventually a diviner with enough CL by passes your nondetection. Legend Lore also works if Elvas is given the scroll so it does not take weeks to get the info needed who or what are you and where you are.<br/><br/>Masquerade will work fine in city if you happen to get resident pendant but from whom you get pendant? Bodies always release questions as no doubt most resident pendant users are not hermits and often than not are well connected in city (why else they would stay long enough to earn resident pendant). Guest cloaks cover you but as said divinations would be used and they will find you eventually if drows are persistent enough. Best chance would had been get into caravan but the gate guards checks no one is disguised in suspicious manner and they would know your wanted.
