History of the Forgotten Realms

The Start of the Twelfth Seros War
Deepwater War
The monstrous wereshark Iakhovas (known as the “Threat From the Sea”) finds an artifact in Coryselmal and uses it to shatter a large section of the Sharksbane Wall, destroying Akhanmyr and one of the Sea Unicorns guardposts in one explosion. The Xedran Reefs take this as a sign that their religious Time of Tempering has begun. Iakhovas and the sahuagin occupy Coryselmal for a time.
