I was referring to the fact that all current non-elder clans (Silvervein, Onyxheart) were founded with/by a bunch of characters that were around for a good couple months (or years).
The Silverveins and Onyxheats had people backing their creation as well as people interested in keeping them running which is why they work. Creating a new clan out of the blue without proper backing will likely see another dead clan with another nullified clan post.
