Think I'm getting idea's formed
The Deer might be called Elidi (Greek for Gift of the Sun) and the Chosen maybe Mariella I need to work out the dynamic though hm
I imagine the deer to be gentle, beautiful, fair, and calm
So either I need a rash, bold, excitable char to counter complement that or I need a similar personally maybe one that's shy, quite, brave, adventurous, and maybe lacking a bit in self confidence
One dynamic is the bold rash one where the Deer keeps her chosen grounded and from flying off the handle while the other one is the Shy lacking in confidence but brave chosen where her deer mothers her and pushes her to come out of her shell
In both cases the deer is motherly in some way but in the first case she may be more like a mothering older sister rather then a straight up motherly type like in the second example
Hm...
I kinda see a seasonal thing going on with the deer too The Male deer the wander is like winter he comes in the winter to the mysterious village while they are performing their generational winter solstice ritual he stays there and finds his wife a Deer that's warm like summer plus gentle and beautiful like flowers she'd be summer then they have a child who is innocent yet wise like Spring and Fall
Though If I was adding the priestess in this the daughter would be spring for her innocence and nativity and the priestess Fall for her calm wisdom
Least that's my thought process on all this lol
