1) He always makes tiny random sculptures for when his siblings visit. (though he mostly makes them for Ares and Kosta).

2) He looks up to both Kosta and Ares quite a bit. Kosta for being brotherly to him and taking care of him and Ares for his fighting and strategizing abilities. (something Helios isn't exactly able to do himself).

3) His missing eye is from when the Turks overtook the island and he tried to fight back but was beaten and lost his eye for his efforts.

4) When he makes a sculpture (usually out of stone or wood) he spends a lot of time making it and trying to get it to be as perfect as possible. In doing this he often spends all his time working on the sculpture and commonly forgets to sleep or eat until it is finished.

5) He owns a cattle farm. And loves each of them so much he gave them all names and cares for them dearly.....

6) He loves to roam around his island a lot looking at nature for inspiration. So he willingly gave Kosta a way to track him if necessary. (for he can get lost in thought sometimes and wander too far and have to spend the night outside occasionally...)

7) He is capable of using magic and his best is light magic. Though he hasn't developed it very well and sometimes accidentally blinds himself or others (but mostly himself).

8) He is in fact entirely missing his right eye. He now has it sewn shut and constantly keeps it covered.

9) He doesn't own a vehicle. Instead he gets around by walking everywhere he goes (unless someone insists on using a car or something....)

10) He ADORES ancient sculpture and art of every kind and basically fawns over any that he sees (carefully of course).

11) He quite often has nightmares, occasionally night terrors, about when he lost his eye. This usually happens when he is alone. (He hasn't told anyone because he doesn't want them to worry). 

12) His usual leather eye patch was a gift. Before that he merely used an old rag tied around his head. When asked about it he'd shrug and say it was the simplest solution.

13) he keeps a small notepad with him at all times (in his belt of wonders) in case he gets sudden inspiration and has to jot down an idea.

14) speaking of the belt of wonders, his belt has four pouches: one on each side, one large one in the back, and one sewn onto the left (this one hangs down a bit due to being connected by a strap). It holds all his tools (that are able to be carried) as well as a couple other items, such as his notepad and some pictures of his family.

15) When walking with someone (family or close friends) he likes to keep them on his right. On the other hand when he is merely talking with them he likes to keep them on his left.
If it is anyone else he strictly keeps them to his left.

You can tell how much he trusts a person by which side he lets them stand on and how close he stands to them.

16) He likes to cling to family and spend as much time as possible/comfortable with them whenever he sees them. Because he doesn't know when he'll get to see them again. (He doesn't leave his island often at all).

17) When stressed he cleans, a LOT. No matter where he is or whose home it is. Though he will deny that he is stressed. He also tends to work more, liking to keep himself busy as not to think about what has caused the stress.

18) He hates himself for being weak and thinks the only think he's good at is art.

19) Hea made a painting of every one of his siblings demonstrating them in their greatest moment. (He does not have one of himself).

20) He loves bitter or tart foods and dislikes sour or sweet foods.

21) he's had five relationships in his life thus far. But none of them worked out...

One was broken off because the girl claimed she couldn't live with his disability.

One was long distance and just didn't work out. (The girl also had found someone else closer to home and was actually very sorry but he understood).

Three had to be broken off strictly because they were human and he is not. He doesn't age and he didn't want to cause suspicion so he made up reasons why he couldn't be with them any longer. He cried each time.
