Losing a character is always a terrifying prospect! And I think it’s very smart of you to try and put in the effort of how things might change once they come back to life. 

One of the first things I think you should do is talk to your DM–do they have any ideas on what he might see once he dies? Will he even remember dying, or would it be like he just got knocked out and woke up later on? If your DM says that your character would remember life after death, that’s something you should explore further with them. What exactly happens? How does your character process all of that? Is it something that he’s afraid of or does he want to go back? Knowing what it’s like after you die can have a HUGE impact on how a person processes living. It might mean that they’re either more or less afraid of dying, which could mean that your guy becomes more or less reckless on the battle field.

But what if your character doesn’t remember any life after death? Does he just take that as “there’s nothing”? Does he take that as there is nothing but emptiness awaiting him when his body goes cold? Or does he KNOW there’s something, and know that he forgot it? That loss of memory can be extremely frustrating, and he could potentially become more focused on figuring that out. 

There are other things to consider than this though, and the biggest thing that I can think of is post-traumatic stress. If anything belongs on the list of things that would cause trauma, I think that dying is a very worthy contender. You may want to figure out if the way he died combined with the aftermath is something that would keep him thinking about it for a long time to come–some deaths may not be traumatic to everyone. My PC Rodney in example is TERRIFIED of drowning, however if he got stabbed? Eh, happens, that’s a part of life. So look at the death that he had and see how that would linger in his mind. Would it make him more anxious? Could it be a source of PTSD? If you do choose to go this route, be sure to do your research to be sure that if he does begin to suffer from some form of mental illness, that you do it justice. (If he already suffers from some form of mental illness, I think it would be VERY important to see how that would collide with the death, what kind of changes it may make. Using Anxiety as an example, would it amplify his anxiety? Would he be more scared of everything? Or would this death be a slap-in-the-face proof to him that he doesn’t need to be so afraid?)

It ALSO could be interesting to see if maybe there could be involuntary changes to him due to the affects of the resurrection ritual. Some DMs don’t have it so you come back right every time. I feel that this post gives some wonderful examples of how you could change as a result of a resurrection ritual. 

Overall ask yourself questions. Ask your DM questions. There’s a quote from the lore of a game that I love that goes, “Ask strange questions. Our questions shape the reality that answers them.” The more questions you ask, the more you’ll be able to figure out how he’ll change. Set aside some time, and try and visualize what he’s going through, where he’s been, how he’s thinking about all of this. Work with your DM to get a clearer view of how things are going for him.

Imprinting: When the dragon hatches, it will imprint on the first character/creature it sees. That may sound really awesome at first, and assuming everything goes well across the intervening decades, it may turn out to actually be awesome for the PC's descendant(s).

Just some of the less obvious issues the PCs will have to face are:

Dragon Fear: Even if it's not in reaction to the in-game action (Frightful Presence), people don't like dragons. Dragons sow chaos in the lives of mortals by destroying crops, eating herds, decimating populations, etc.

Food Supply: Congratulations! You've got a brand-new, freshly-hatched, baby dragon. Now, what are you going to feed it? That sheep? Sounds good. Now what about tomorrow? What about in a few months, when a sheep doesn't even count as a single meal any more? Are you really going to keep adventuring just to watch your treasure horde dwindle from the costs of keeping that beast fed? An adult dragon may be able to go weeks or months without a huge volume of food, but you've got a ravenous, growing predator on your hands. It wants... no, needs food. "Feed me, Seymour!"

You're "Mommy": Ever tried to get rid of a 5-year-old who really wanted to stick around? Now imagine that delightful child can kill you accidentally, while playing with you. Even if you decide you don't want to keep said hatchling around, you've got to convince it to leave. You might shoo it away, only to have it show up again at the worst possible moment. Or, you leave it staked out in the forest, only to find that it's strong enough to break loose, and meet you in the town market. Or on the roof of the Inn where you're sleeping.

not a fey but a rakshasa- my players were bargaining with her for magic items, and some of the prices she asked were "your dying breath," meaning a permanent failed death save, or "your rest," meaning a wis save for each long rest, otherwise the player is tormented with nightmares of the hells and takes a point of exhaustion
