Brinelin

Brinelin is the Zendikar Moon Kraken that ruled the waters of the bays of Akoum.

History
Brinelin is a millennia-old moon kraken who rules the seas off the shores of Akoum in Zendikar. He is hard of shell and possesses many claws and tentacles that have only grown stronger with age. All the lesser creatures of the sea obey Brinelin, and the kraken demands tribute from each ship that passes through his territory. There is very little that Brinelin fears, but Sorin Markov, is one of those things.

Brinelin demanded tribute from Nissa, Sorin, and Anowon when they traveled together to the Eye of Ugin. Sorin casually killed a goblin to satisfy the great creature. That tribute was found lacking, and Sorin revealed his true nature to the creature. Brinelin remembered Sorin and was somewhat terrified to find him returned after so long, but would still not let them pass. Since Sorin's intimidation had failed, Nissa gambled that her diplomacy might work. She spoke of Sutina, the fallen leader of the Tajuru elves, who had been friends with the kraken. Greatly saddened by the news of his friend's death and discouraged by the return of the Eldrazi, Brinelin finally acquiesced to lead them safely through the crystal reefs.

Trivia
Based on his friendship with Sutina, Brinelin was an earlier iteration of Lorthos, the Tidemaker. Apparently, that was his original name in development, and it was changed for the final set, but the author of the accompanying novel didn’t get the memo in time.
