[@Xaltwind] Gotcha! 

Eh, I suppose the idea was making a child who is mature and not mature for their age, and has a unique sort of nature or class/ability from that. Like an accursed bloodline of some sort, though their bloodline just being cursed in general could maybe facilitate that perhaps, that gives them boons with a lot of downsides but also at least 'some' unique talent or another. The unique boons come with distinct banes, in other words. Not that i perhaps worded it so well above. Apologies for that and other, ah, toe stepping on i might have done there. ^^;

Of course not making them reliant on the isekai'd guy is fine, i was just thinking of a way to spice up getting them to meet the person in the first place. So no worries there, my friend! XD

And as ever, thank you for answering my questions! These have been very helpful indeed! :)
