CHESSU

A species native to the Delta Quadrant. In 2377 the Aksani participate in the inaugural Antarian Trans-Stellar Rally. That event is depicted in [#149 Drive]. The Aksani are to host the post-race festivities but then the Chessu insist upon that honour and the Aksani threaten to withdraw from the Rally unless they are permitted to retain the agreement. This puts the race co-ordinator O'Zaal in an awkward position until Janeway devises a suitable and diplomatic compromise for all parties involved, namely that U.S.S. Voyager host both the pre- and post-race festivities.

O'Zaal's assistant interrupts the meeting between Janeway and the race co-ordinator, Ambassador O'Zaal. The ambassador takes the call on Janeway's personal computer.
O'Zaal: "I asked not to be disturbed."
Assistant: "I'm sorry, but the Aksani are threatening to withdraw unless they're allowed to host the post-race ceremony."
O'Zaal: "Did you explain that we've already promised that to the Chessu?"
Assistant: "Yes. They said that was unacceptable."
O'Zaal: "Arrange for another meeting. I'll have to find some way of appeasing them." Janeway and Chakotay, in the background, overhear the conversation.
After the transmission, O'Zaal to Janeway and Chakotay: "Well, I hope the race you've just entered doesn't end before it begins."
Janeway: "It's that serious?"
O'Zaal: "The peace is still very fragile. Every decision I make, no matter how trivial, is looked upon as symbolic."
Chakotay: "So every time you make a concession to one participant-"
O'Zaal: "Another is offended, yes."
Janeway: "Maybe we can help."
O'Zaal: "That would be wonderful, but how?"
Janeway: "By providing neutral ground for the pre- and post-race activities. Since we've never taken sides in your conflict you couldn't be accused of showing favouritism."
O'Zaal: "If your racing skills are as sharp as your diplomatic instincts the other teams won't have a chance."
