Keen uploading here! Small explanation, in order to transport Kel’thuzads remains, Artie shoves them in an urn that contained his father’s ashes. How he managed to fit the corpse in there is nicely explained here! Next time you fight KT, take a look and see the result of Arthas’ laziness!
Now the real tension begins! Will Arctic and Sunisa find food before they discover how delicious Keen really is!? Oh noes!
