Eldritch is the ruler of a small magical realm called The Snowglobe; there's a little bit of info about it on his profile if you're interested! I haven't quite decided how royalty/leadership works in their realm, but Eldritch's parents weren't the previous rulers, so I assume they have a different way of picking rulers besides having them be blood-related.
Eldritch loves his world and is proud to be the king of it, doing everything he can to protect his subjects and make their lives easier, even at expense to himself. However, he does tend to stress a lot, and worries that he isn't doing 'enough'. (He also has a kind of permanent amnesia that really doesn't help his mental wellbeing at all.) He has an adviser, Irving, who helps him make important decisions as well as assists Eldritch with general royal duties. Eldritch doesn't like needing to ask for anyone else's help, but accepts that he needs it sometimes.
