Does the thread mean that they always have a general idea of where the other is? They're trying to track down Eggman and Sonic's like "my... Eggman sense... says we should look over there" lol (sorry about the multiple asks I just think this is a really interesting concept)
no its okay tysm!!
it gives a sense of what direction the other is, since theyre physically connected to each other, but (for the most part) not much else
I'm still thinking about how itd work and not sure what exactly I want to do, but I think that they could sense certain things about the other only if they actively tried. grabbing the string and purposefully tugging on it would make the other person feel that
I think soulbonds could have the potential to allow the people to sense each other in a more emotional sense, but only if those people work on that connection and want to keep it open. eggman and sonic are very pointedly Ignoring their bond. I think the most they would get is vague intent? for example immediately pre unleashed, sonic would get a Very Bad Feeling and Know its from eggman. no details or understanding why, but he knows its from the soulbond. it has to be really intense for the other to feel it since they dont have any open connection
but still just knowing the direction would be enough, and sonics friends always joke about sonic having some eggman radar because he can sniff him out really easily and sonics always like yeah haha lets move on to a different topic!!
