I am not sure what you mean with 'steward'.
Only the founder (as in, the exact character that created the guild) has the ability to reclaim his founder rank (rank n°1). No one else will ever be able to claim rank n°1. Only (s)he will get the link to be reaffirmed as founder.
There is, however, another functionality. If Founder leaves (rank 1) and you only hold elder rank 5 (so rank 2,3,4 are left unused), you can reclaim the highest rank position.
What this means is:
- Ranks 2,3,4 get deleted
- Your rank, rank 5, is made rank 2
I think you're looking for this option.
