One of three innocent Bajorans executed on Terok Nor for an attempt on Gul Dukat's life, whose place Sisko occupies in the shared vision of Things Past.
Ishan Chaye is a Bajoran whose fate is at the centre of the Deep Space Nine episode Things Past. During the occupation he and two other men, Timor Landi and Jillur Gueta, were arrested after a bomb attack aimed at Gul Dukat on the Promenade of Terok Nor.
They were innocent. Odo, new to his post as security chief, accepted the evidence against them without digging further, and all three were shot. He has carried the guilt ever since.
In 2373 a plasma storm links Odo's mind with those of Sisko, Dax and Garak, and they relive the events as the condemned men. Everyone on the station sees Sisko as Ishan, and he comes within moments of sharing Ishan's death before Odo finally admits what he did.
