Well, if we can have a Japanese man named "Sulu."Going only from photos, she looks like the right type, allowing for being Korean rather than Chinese. But then, "Chen" can be a Korean surname as well.

Any suggestions for Gell Kamemor from Rough Beasts of Empire and Serpents Among the Ruins? I keep getting a Linda Hunt vibe from her (though she's never described as being that short). She has a somewhat reluctant Hetty-like authority about her; she doesn't want power, but one crosses her at one's peril.
