((A miracle of Aethernet connection has happened!
This turn is maddening, awesome and absolutely hilarious (many thanks, ironsnake345). Hereby, I put request for Mortal Combat: Prismatic Dragon versus Duck-Island!
As for music... "Bye Bye Life" from the film All That Jazz seems oddly appropriate from a mage perspective.))
First several seconds, Kahel was too stupefied to think of something to say. No mage in his sane mind would use mimic's heart for such unstable transformation. Entirety of possibilities - wasted in a single gulp! Impossible! Absolutely impossible!
Then, the fear came. Mage turned prismatic dragon, mage that Kahel has wounded, stood now far above, taller than mountains, his wings shadowing entire island. There were no hope and no rescue from it's wraith. Prismatic breath, most potent of weapons, shredded ethereal and real with same easiness. And what magic could hope to subdue the beast in time?!
Thirdly and lastly, Kahel the Changer, one of the greater warrior mages of the Duck island, finally came to his senses... Partially, at least:
"Ahahah! What a majestic ending! Behold the treasure wasted on an ultimate revenge possible against this very land!"
Mage paused, finally realizing the imminent danger he was in.
"Ah well, why bother with pathetic speeches... Xazoliomuhr? I was extremely pleased by your service. Hereby, I declare our contract finished. You may save yourself or follow me to seek even greater crusades and many souls to reap - now, it's entirely your choice to make."
If distance seems reasonable, run to the Whirlpool. It's bad luck to follow the way you arrived, side-by-side with those you just tried to kill.
Otherwise, follow the road of the Damned, as seen by souls and shades venturing back through the main portal.
...
A mad laugh could be heard as the island crumbled to its inevitable end. A malevolent shade empowered by deaths and made ethereally incarnate, walked to the eldritch portal along with things long gone and things that were never made known. Shadows danced along the battleaxe edge while content grin stretched eerily on a face of the mage once dead.
"Run, run for your lives, insolent mages... For the Death itself walks in my wake. Cycle is endless. Welcome your Oblivion now for the life to rise anew!"
