The Unwelcome Warlock () von Lawrence Watt-Evans

The Calling. Sooner or later, it claimed every powerful warlock . . . a growing magical compulsion to go north to the mysterious land of Aldagmor that nothing could stop. None ever returned. Hanner the Warlock knew his days were numbered. The Calling pulled at him ceaselessly now, and his ability to resist had begun to crumble. So he determined to find a place where the Calling couldn't reach him . . . another world, located through a magic tapestry. Every warlock knew that the farther he was from Aldagmor, the weaker the Calling was - and the weaker his magic was, as well, but that was only a secondary consideration. That weakening had given Hanner the idea to find, or make, a place so distant from Aldagmor that the Call couldn't reach it at all. Unfortunately, the Call took him anyway. And that's where his story really gets interesting. Because the Calling wasn't what everyone believed. And when the warlocks who had been Called over the decades suddenly woke up again at the object doing the calling - and found themselves without their powers - their world may never be the same!
