The only obvious choice is to embrace your new destiny(you laugh a little inside at the pun) and become a predator. With Destiny's help, you quickly master the use of your new body(in more ways than one) and soon the two of you are equal predators, and soon dominate not only the entire beach, but the first 100 feet of the jungle as well. Your new body doesn't age, which means that you have eternity to rule over your territory. You and Destiny raised many broods of nagas together, and eventually, through feeding on the scattered human tribes as well as the other natives, you gained dominance over the entire island. Many centuries down the line, in one of your moments of reflection, you realize you never did remember seeing your friends again. You shrug, knowing that they fufilled their place in the cycle, just as you now fufilled yours.
