Crenshinibon, also known as The Crystal Shard, is a very powerful and evil magical artifact.
Description[]
...
In the Icewind Dale game[]
Crenshinibon is not available to the player as an in-game item.
Instead, it is used by the devil Belhifet in chapter 6b to 
break the wards protecting Jerrod's Stone in Easthaven, build the ice tower Cryshal-Tirith around it, and reactivate Jerrod's Stone as a portal to the lower planes in order to start an invasion of Icewind Dale.
