The Fourth Sending of Darkness

Ilservian's surviving friends became corporeal once more and raised the Thorns, using them to alter the patterns of magic in the world. But Isin Dule had misgivings. He remembered the final days of the last war, his friend's blank expression when the planar energy was felt, and the compulsion that had come upon him. “It is likely a trap, brother,” he told Ilservian, and still they had gone. <ref name=PY11/11> 2000/11 - Should the Stars Fall - Should the Stars Fall/The Child of Daralet--Leafcull to Frostfell, PY 11 / (November to December, 2000)</ref>
Isin Dule's faction of shadows seemed alarmed by the Hopeslayer's blind rage, and appeared to be working to keep him imprisoned.<ref name=HistoryDerethIX>2000/08 Twilight's Gleaming - General History of Dereth Vol. IX</ref>
Isin Dule turns upon his childhood friend, and, brooding in the wastes, steered a fateful course. He took his portion of the Shadows into his confidence, telling them that the pieces of the council's trap must be protected. If his friend should be released, he feared it would be the end of all. Ilservian was not fully in control of his own mind. What would happen after his vengeance was slaked? The price that the darkness of the wasteland would demand of them was not yet known. But Dule's first attempt to stave off disaster failed. The humans of Ispar gained access to the Nexus Facility, and a second piece of Ilservian's prison was destroyed. <ref name=PY11/11> 2000/11 - Should the Stars Fall - Should the Stars Fall/The Child of Daralet--Leafcull to Frostfell, PY 11 / (November to December, 2000)</ref>
