I remember those guilds from either the old NA server or the European server that closed down, and former members may not have remade those guilds here on the adept server. I do know there are several good guilds available, and you might start with looking at people advertising on these forums as they look for new members. Otherwise, you can ask in world chat for recommendations or use the guild search tool that was available in game at the guild registrar. Oftentimes it is best to locate a guild whose members have similar playtime as yours. I know you know that a good guild is immeasurably useful and helpful as you restart your new journeys in DP.
Best of luck to you, and safe journeys!
