Oh, I LOVE [name_u]Ember[/name_u] (suggested above) with her sisters. It’s fantastic stylistically, and the symbol is great.
I was thinking that since they already have a sky name and an earth name (moon and flower), a water name would be a perfect fit. Then each daughter has her own little realm.
[name_f]Delta[/name_f] (suggested above- I’ve been loving this name lately)
[name_u]Or[/name_u], if you want her to have double images, like [name_f]Lilia[/name_f] [name_u]Wren[/name_u], [name_u]Ember[/name_u] [name_u]Brooke[/name_u] would be astonishing. [name_u]Fire[/name_u] and water. To me, that’s the name of a girl who can both ignite and soothe her world as the need may be.
