When I did my research for name options for my sylvaris (I have 2), I looked into all of the plant-world genus (plant, flowers, trees, etc.) and I tweaked the spelling a bit. One flower I found which I liked the sound of was Nicandra, so my necro is called Neecandra. As for my warrior, I wanted her to have a more robust ancestor from the plant-world, but yet still sound feminine, so I retained Aglaia (a tree from the mahogany family), and tweaked it into Aglaiae.
