Cloven Crystal

The Cloven Crystals are three magical items that resemble an amber cat's eye. The Crystals are critical to releasing Uk'otoa, acting as keys to its confinement. It rewards those who use Crystals to free it with control over water.

Description
The Cloven Crystal has an amber-yellowish color. It has striations that refract light around it. At one end, there is a pointed oval line carved in about three inches across. With all three crystals deposited, Uk'otoa can be released to rule the Lucidian Ocean once again, just as it had done in ages past.

Background
According to Avantika, Vandran already had a Cloven Crystal when she met him. Avantika and Vandran discovered another Cloven Crystal was being auctioned off in Port Damali. They stalked the collector who bought it to an unknown island and killed him. Avantika absorbed the crystal, causing Uk'otoa's eye to appear in her palm.

When Vandran abandoned the quest to release Uk'otoa, he took one Cloven Crystal with him. If Fjord's vision of Vandran absorbing the crystal was accurate, it means Vandran found a way to get the crystal out of his body. He kept it in a hidden compartment in the captain's quarters of the Tide's Breath. Avantika failed to find him or his crystal. She hired the Jagentoth family from Shadycreek Run to find a crystal and deliver it to Nicodranas.

It is unknown how a cloven crystal ended up in a safe house owned by The Gentleman or if The Gentleman is aware what the cloven crystal is.

 In the subterranean tunnels of the Labenda Swamp, the Mighty Nein found a Cloven Crystal resting in a pool of water. Fjord touched it and immediately entered a dreamlike trance, during which he saw a vision of his mentor, Vandran, standing over a body, thrusting the Crystal into his chest, and summoning the same falchion that Fjord wielded. Fjord also thrust the Cloven Crystal into his chest. After this incident, the falchion appeared to have a Cloven Crystal resting within it.

 After killing Lorenzo and the Iron Shepherds, the Mighty Nein searched the house for evidence against the Jagentoth Family, who employs the Iron Shepherds. When they turned Lorenzo's Bag of Holding inside out, they found a letter from Avantika.

Fjord recognized the drawing in the letter as the same orb that he absorbed in the subterranean tunnels of the Labenda Swamp.

 Captain Avantika revealed that she had a tattoo on her neck that resembled a Cloven Crystal. She also showed Fjord the Cloven Crystal resting in her right palm.

 Captain Avantika deposited her Cloven Crystal in the Temple of the False Serpent on Urukayxl and is rewarded by Uk'otoa with the power to control water. After escaping the temple, Avantika and Fjord met her quarters. She told him about having known Vandran and that Vandran had the Sword of Fathoms. Avantika saw through Fjord's attempt to lie that he did not know Vandran. She seemed to already know that Vandran was dead, but did not know the location of the shipwreck. She convinced Fjord to show it to her on a map. Avantika said the Cloven Crystal was likely there because Vandran would have kept it with him at all times.

 After failing to find the third Cloven Crystal in the wreckage of the Tide's Breath whilst exploring the Diver's Grave, Fjord later discovered and absorbed the Cloven Crystal within the lair of Dashilla. He received a brief vision of Uk'otoa, and after coming out of the vision, saw that his falchion now had two eyes, one in the hilt and one in the pommel.

 After the Mighty Nein defeated the deep scion and chuul guarding the ruined temple located underwater at the Gravid Archipelago, Fjord deposited one of his Cloven Crystals at the location and was rewarded with the power to cast Control Water. Uk'otoa also gave Fjord a vision of the third and final temple's location.

 Fjord freed himself from Uk'otoa, throwing the Sword of Fathoms with the last crystal into the lava pools of the Cinderrest Sanctum. The sword sank to the bottom and Fjord believed that the crystal was destroyed as well.

 Uk'otoa sent three warlock deep scions and a crew of sea spawn to retrieve the remaining cloven crystal from Fjord's body, revealing that the crystal in the Sword of Fathoms was only symbolic of the crystal still within Fjord.

 After the attack on the Ball-Eater while sailing near Urukayxl on the way to the peace talks, a Greater Restoration spell allowed Fjord to vomit out the remaining crystal, and it was placed in Caleb's Vault of Amber for safekeeping. The next morning, the group discovered that the leader of the assault had a tattoo of a Cloven Crystal on his chest.

 When Caleb used Vault of Amber to store some of Beau's fireworks, the Cloven Crystal apparated for a short time before being covered in fireworks. Fjord noticed no visible changes in the crystal's appearance.

 In the attack on the Midnight Hammer, one of Uk'otoa's minions (a deep scion) located the Cloven Crystal hidden within Caleb's amber necklace. The deep scion dispelled the Vault, shattering the amber to reveal the Crystal, which fell to the icy deck (along with Beau's fireworks).

 The undead Avantika recovered the crystal from the deck and dove overboard, pursued by the Mighty Nein. Fjord succeeded in killing her and recovering the crystal, which he placed in his Bag of Holding.

Summary

 * First Crystal: Currently in Fjord's Bag of Holding.
 * Fjord found the crystal in subterranean tunnels of the Labenda Swamp and absorbed it into his chest. Avantika had hired Ionos Jagentoth to recover it for her, telling him it had been stolen from her, and he subcontracted with the Iron Shepherds. It is unknown how it came into The Gentleman's possession.
 * The crystal remained in Fjord's chest until Caduceus's Greater Restoration removed it. It was placed in Caleb's Vault of Amber. When the vault was dispelled and Avantika briefly recovered it, Fjord placed it in the Bag of Holding.
 * The crystal was inadvertently stolen by the Tombtakers when they took the Mighty Nein's Bag of Holding.
 * Second Crystal: Now in place in the temple of Uk'otoa on Urukayxl (placed by Avantika)
 * According to Avantika, Avantika and Vandran discovered the crystal had been auctioned off to a collector in Port Damali. They stalked him to an unknown island and killed him, and Avantika absorbed the crystal.
 * Third Crystal: Now in place in the underwater temple in the Gravid Archipelago (placed by Fjord)
 * The Mighty Nein recovered the crystal from Dashilla's lair.

Trivia

 * According to Avantika, Vandran already had a Cloven Crystal when she met him. This seems to confirm the accuracy of Fjord's vision of Vandran absorbing a Cloven Crystal after killing its previous owner.


 * When the Wildmother spoke to Fjord in, she mentioned a dark seed that she couldn't heal, buried deep in his chest. This dark seed was most likely referring to the Cloven Crystal.


 * Fjord's eye color closely resembles that of the Cloven Crystal and Uk'otoa's eyes.
