This is one of the oldest areas I know in the server which have remained largely intact. I have a relationship of love and hate with it and here's why:
1- It is a temple of a god of thievery and the owning sign is outside the temple. As a former owner of the temple I can tell it is a huge problem and knowing two other owners, they have also dealt with a lot of prejudice just because your name is in the sign. It's also worth mentioning a high traffic of scry thrown at the owners of the temple. A change to fix this would be very simple and align with most "secretive" headquarters or rooms in the server, which is moving the sign inside.
2- It's "scriable", if there's an area that deserves innate scry protection it's the temple to the one who was a god of intrigue and secrecy. It's a bit uncomfortable to have to constantly apply protection from scry and hit something because majority of members are rogues lol
3- It's not a guildhouse. This isn't even a big deal, to be honest. But it feels it should had been a guildhouse. But the owner is subject to any member strolling in and taking anything from what could be a personal chest.
4- The two locked rooms are not connected to the main guild area and you have to wander through "public" areas between them, exposing yourself. Yes, it is rare, but I've encountered people in there who saw me hauling heavy stuff before.
I don't think it needs a big overhaul, I sort of like it being a super old area. I just wish it had better tools to help rp and prevent metagaming.
