the tl;dr version is dear ol' dad is heavily involved with he slayers. his two boys became a part of the slayers because their dad is a legend and they too in his shadow are legends. all three of the kids have the same mom and we have her as abigail in the bio's but i'm sure that could possibly be changed if we find the mother.
as far as ryver goes he was a problem child. he was sick, had asthma, type 1 diabetes, adhd, dyscalculia, and tourette syndrome. he was put in special education classes. and when he was in high school he got into a nasty accident where he almost lost his life because his lung was punctured.
ryver has a son who is almost three and bradyn has a crew of kids.
