Federation Eelstock Convention

The Federation Eelstock Convention was a social gathering of Starfleet officers in the early 2300s. In some cases, it has been used as a political forum; most notably, one to discuss the situation with the Klingons (at a time when the Federation was at war with the Klingons). 

Rivera Gotens met up with old friend Admiral Daniel at one of these conventions. But years later, after the two would meet again, only Gotens would retain memory of his old Trill host meeting Daniel. ("The Tiloniam System", "The Tiloniam System: Remixed")
