As for Venat and her likely age... well, she's old enough to have retired and kept on going, so despite having no apparent age and not seeming older than the others, logically she's more towards the "cool old lady" archetype.
Also it's possible that Venat still does some work with the Convocation as an advisor even if she's not an actual member any more.
