Toran arrived at Deep Space 9 in 2370 in order to oversee the return of three members of the Cardassian Underground. Toran and Garak were already familiar with each other at the time of this incident, and viewed each other with hostility. Toran convinced the Central Command to have the dissidents killed, rather than exchanging Bajoran prisoners for them as Garak had suggested. Toran gave Garak the task of arranging an appropriate "accident" for Lang and the others to regain favor on Cardassia. Garak killed Toran – vaporizing him – when it became apparent Toran had no intention of keeping his word.
