The death of Yajnev engulfed Vetetrandes in an opaque impenetrable lock.
Yajnev is an actor who's will is infinite but localized. Its nervous system dictates localy occuring events, as well as the course of Time. Anyone entering Yajnev is effectively vaporized and assimilated into the tendrils of Yajnev.
The space, and time, surrounding the corpse of Yajnev is animated by its reflexion and thoughts. The effect of the Immigrats approaching Dinaisth might have caused the collapse as they forced their way through the Soies.
