The Cyrollans and the Lôxôni were of its oldest members. The Symbiotry discovered the Krynn "centuries ago" and were one of the most recent additions. The Cyrollans contacted United Earth in 2308 to invite humanity to join the Symbiotry, and gave them a decade for a definitive decision to be made. Humanity accepted the offer and became the newest members in 2318. Thanks to Ambassador Jhessela's assistance and the efforts of Gage Blackwood, humanity retained the Legacy of Time and a peace agreement was finally made between the Quo'thalas and the Symbiotry.
