Finally! So they went with 16th-18th century Japanese names for the Raen and ~15th century Mongolian names for the Xaela, then.
I'm not sure how closely I'm following the rules, but K'raitra Tsunhe shall soon be Sayuri Reiketsu (I do not even want to attempt trying to find something acceptable with Mongolian origin so Raen it is). Sayuri is the equivalent to an orange lily and Reiketsu is akin to cold-bloodedness/coldheartedness.
The forename seemed to be something beautiful found in nature and the the surname something related to battle/profession so that's where that ended up.
Fun fact: K'raitra has typically been Kiraitra in all the other times I've used it. Kirai means a hate/great dislike and supposedly orange lilies signified hate/revenge in the Japanese language of flowers.
