The whereabouts of the Crystal Shard were simply too elusive. Take Faerûn, for example. The Crystal Shard was indeed famous throughout Faerûn, but in reality, since its creation, it had caused trouble there fewer than five times in total.
There were simply too many planes in the multiverse. It held no particular preference for Faerûn, so it rarely appeared there. Over the past several thousand years, the Crystal Shard had completely vanished from Faerûn, to the point that many believed it had already been destroyed by some powerful deity in the Astral Plane beyond the void.
That was why Solam had considered the Crystal Shard theory unreliable from the very beginning. What were the odds of such a coincidence?
Yet such coincidences really did happen. After seeing that black crystal tower, Solam felt that his luck was good enough to buy a lottery ticket. This particular trait of the Crystal Shard was simply too famous.
Still, that explained Trism's reaction, as well as that of the shadow assassins.
The Crystal Shard possessed a highly unusual curse ability. It continuously influenced nearby creatures through subconscious suggestions. As long as a creature was detected by the Crystal Shard, it would keep making suggestions, gradually dragging the target into an abyss of destruction and evil. Its effect was equivalent to the fifth-level mage spell Dream—or its opposite, nightmare.
Crenshinibon's "suggestions" were generally meant to stir up chaos and evil while expanding its dominion over a wider area. Thus, its influence over evil creatures was especially great! Wasn't Trism a textbook example of an evil creature? First, he was half-Drow. What sort of creatures were Drow? Almost everyone knew. Second, he was a werewolf, and the bestial savagery of werewolves was unquestionably evil.
Crenshinibon could fulfill its desires by repeatedly casting Suggestion without limit.
