Wixiban was a Talaxian and an old friend of Neelix. In the past the two had worked together on several less than legal ventures. The last of these had landed Wixiban in prison.
The two met several years later on the station near the Nekrit Expanse where Wixiban had been stuck for three years due to debt problems. Wixiban succeeded in drawing Neelix back into his schemes. However, Neelix had a change of heart and helped Wixiban to escape his predicament. (VOY: "Fair Trade")
