You're looking for /m/KbinRequest, per that magazine's sidebar:
This magazine is for requesting owner privileges for an abandoned magazine or to replace inactive owners you currently moderate.
However, also per that sidebar:
This magazine is currently inactive until a proper moderation team is added. Don't request anything until an announcement is made.
Doesn't look like there's going to be a process for this for a little bit yet. I suppose in the meantime, you could make a new backup magazine for /m/drama content, and then close it back down once ownership transfer tools are available.
