Just doing my little part. I've added the Persian names. Immortals => Anusiya : according to the historian Kallie Szczepanski, was the name used in the empire (meaning "companions"). Satrap's Court => Vyxsachapavan : means "Court of the protector of the land" according to Herbert Cushing Tolman (vyx, meaning "court"/"palace" + xsachapavan, "meaning protector of the land"). It's a bit bizarre, so we can also use the more agreed on "Xsachapavan" (so same case as for the Mongolian UB2 : the name of the institution more than the building itself).
