1. where do they reside? do they like it?
Marcosias lives in the underworld. He was born there, never really knew anything different. He doesn't like or dislike it
2. are they an edgelord or a cinnamon roll?
In the middle? He's very much a man, neither dark and brooding (most of the time), or sweet and innocent.
3. do they escort souls to the afterlife?
Nope. He's the king of the underworld. That's the job of those employed to do such things!
3A. if yes, what do they think of this job?
3B. if no, what do they think of the idea of having to do this for every single mortal soul?
The way death works in his universe is that when one dies, they are judged by one of the king's men, and if they are found worthy of living a new life or finishing their life in the underworld, their soul is brought there, where they live out their life until their second death. Most souls will dissapate on second death (or first in the case of those born in the underworld), but occasionally some will be reborn in a new universe. Sometimes as a punishment and sometimes as a reward, depending on the circumstances, luxuries, and hardships of their new lives.
Marcosias finds the idea of personally judging souls archaic and inefficient, as did the previous king and the king before him. This new system started when the world's population really started growing.
4. what do u think makes them different from other death gods?
He's not really a god. He's just a king. And even then, he wasn't born into royalty. He just happened to be one of the many decendants of the first king of death, participated in a tournament to find a new king, and won.
5. what is their temperament? what about personality types?
Above all, he's lovesick, but he's also sure-headed and a bit cocky. He tries to stay serious, but he's a dreamer and finds himself ruled by his dreams and his emotions. Over time he does mature, but he'll never truly be the regal presence his predecessor was.
6. what are their hobbies?
Singing, dancing, writing so-so songs, spying on the girl of his dreams, anything that takes his fancy.
7. what is their aesthetic that they would like?
Very big band/swing with the pinstripe suit and fedora. He's definitely inspired by the overworld's roarin 20's.
8. what symbols do they have? ex. for thanatos it would be the black rose bc fancy and pretty and edgy except this rose would have a black stem, also black swans
His scythe (Which actually looks nothing like the image in his profile), which was passed down to each new king as a symbol of royalty.
9. what are their fave colors? do they like the color black?
He finds the color black to look quite dashing on him, and it's typically tradition that the king wear darker clothes, so win for him! His favorite color, though, is actually pale blue.
10. what are their fave animals? are these animals symbollic for them? are these animals considered omens in the world of the living in their universe?
He doesn't have a favorite, per se, but he does have a good friend who was originally a lion.
11. i think the death seasons are winter (more common i think) and summer (underused in my opinion, perfect for a fire elemental). is ur oc associated with either one of these seasons? what about fall (i think this could be a neutral element since it is the opposite of spring)?
Nah, he's not really associated with a season. He just has more work to do doring the months where more death occurs.
12. what elements are they associated with, if any?
The scythe of the king does command a shadow army, but he himself is not associated with any element. He also has a magical artifact called The Mask of Ifrit, in which the mask transforms the wearer into a being of pure flames with a molten rocky core. He will occasionally use it as it does give him a boost in strength, speed, and stamina, as well as an extra layer of intimidation if he ever needs it.
