BIO:Ardox is the only botanist capable of maintaining a crop of arctic chloridia, a strain of the plant which has been extinct since the time of the ancients before the beginning of the old kingdom, when the spirit keepers had to take drastic measures against a major threat to the world at the time. Long story short, they ended up changing the climate of their environment, and essentially eradicating all of the arctic-type terrain on the known map of Letalis.
