Becoming Uktena (Rank 6)[]
The legends of the Cherokee say that a man was transformed into the Great Uktena to try to kill the sun. Great Uktena was around long before the Cherokee, but Garou have taken the form of his children on two or three occasions. Great Uktena teaches this Gift only to the most worthy of his Uktena followers; with it, the hero may transform into a creature even a Thunderwyrm would fear. After the crisis is resolved (assuming he lives), the new uktena slips into the nearest body of water and into the umbra, forever parting with his Garou brethren to join his father in Galunlati. Such a glorious end to an already legendary career is worthy of fireside retellings for generations.
System[]
Once taught the Gift, the Uktena may call upon it at any time by invoking the Great Uktena. The initial stage of the transformation takes three full turns, during which the werewolf's body grows and changes to a 20 foot horned serpent. The new uktena still retains the personality of the Garou at this point. After a period of time (usually no more than a scene), the final stage of the transformation begins as the mind of the Garou recedes and the uktena mindset takes over. The spirit creature heads unerringly towards the nearest source of water wide enough to encompass its diameter (not necessarily its whole bulk). As it slides into the water and crosses the Gauntlet, the transformation is complete; the hero's former pack had best treat this uktena like any other of its kind.
