Great. While I don't want to step on the toes of long established rules I'm all for seeing things in context. Having rules to prevent an onslaught of new characters clump up shards is very important, but if someone was to stick around for a few weeks/months I could see them participating in shards even if they aren't officially acknowledged.
Also, the point of times without proper Councilors is also valid: personally I don't have a problem with literally any other Councilor checking Apollo for Seer affiliations and acknowledging him.
