I'd say sage is the odd one out. While it had historical significance in classical and medieval Europe, I don't know anything about sage as a luxurious trade good. Incense was also used in India (by the Indus Valley Civ already), Tibet, China. Most of it involves agarwood or sandalwood, which are native to India and Southeast Asia. Any 2 territories in India would be good. Maybe Ganges and Maha... West India?
