In one possible timeline, the Alsurans were an intelligent species native to a region of space near the Krenim Imperium. The Alsuran Empire was erased from history by Annorax's weapon-ship. The only evidence that they had ever existed was an example of their food, saved by Annorax aboard his ship. This dish was served at a dinner prepared for Annorax, Chakotay, and Tom Paris in 2374.
