Tucana

"one created from the stars doomed to burn out"
Tucana, born within the safety of the stars came down to visit the earth fully knowing, he wouldn't be able to re-enter. When you are born in the stars you get to live forever because of certain chemicals, or lack of, in space wont let you die, but leave the confines of space you will soon be doomed to meet your demise.
When Tucana came to earth he landed in a small town that recently crowned a new king, Wonderland, Tucana went to see the new king fully expecting to be outcasted from their land, instead of that he was welcomed into the palace with open arms, where he grew a liking to the king and queen.
Sooner or later the king and queen both announced to Tucana that they both shared feelings to him,
overcome with joy of someone actually liking him for a change, he agreed that he two liked them both and soon he was two crowned king.
Now days he resides in the palace taking care of all the important things as it makes him feel ever so happy, he also takes care of all their adopted children to make sure they are all loved as well as not making them feel left out of anything as well.
Little to his knowledge he is slowly dying. Everyday gets more and more painful for him but he just brushes it off as overworking himself. But even now others are starting to notice a change in his appearance as well as some of his behaviour patterns as they are becoming more and more erratic.
