Hyacinthe

Hyacinthe is an alicorn (formerly a unicorn) found by Umbra, Alethea, Nysbith, and Ipepis. Hyacinthe resurrected Ilytherra Silverbow after her party mates helped clear the corruption in her lair.

Hyacinthe is bound to Ilytherra and acts as her familiar.

History
Hyacinthe was a unicorn born and raised in one of the many beautiful unicorn lairs. However, her lair was plagued by a corrupted being. After encountering a group of adventurers who warded off the evil, Hyacinthe was then asked to revive the lifeless body of Ilytherra Silverbow. Using a special gem, Hyacinthe was able to do it, however, the two were then bounded.

Becoming Onyx
After Ilytherra's family was killed, the soul that bonded at Ilytherra and Hycaninthe together started to corrupt, drastically changing the unicorn's appearance. After Ilytherra had brought Hyacinthe to the temple of Shar, she baptised her under the church of Shevarash, turning Hyacinthe into a shadow unicorn. Hyacinthe then changed her name to Onyx.

Returning to her Roots
After Ilytherra pledged herself to Corellon and renounced her faith in Shevarash, Hyacinthe was then turned into an Alicorn, blessed by Corellon's light.
