When you make friends with an Omnigod like GrineX, the constructs of 'body' and 'spirit' begin to get a little hazy. Long ago, Mera somehow found her way into Zeoxian lore. It's hard to tell who Adelle is. Is she a true piece of Mera? Do they share the same space or even the same mind or personality. It kind of becomes unclear in the grand scheme of things, especially when you end up as a priestess withing the world of a powerful Omnigod.
In either case, none of the dragoness' sweetness is lost between iterations, so she'll continue being cute and adorable as long as she draws breath
