Just wondering - are jade bloods the ONLY ones who can care for the mother grub, or can other castes care for her as well? I have an indigo blood oc and her and her ancestor are basically supposed to be the momthers of the group so I figure it would be fitting for ancestor to have helped care for the mother grub - but I don't want to be going against canon.
Canonically, I believe it was only Jade bloods, but there are plenty of ways to have your indigo troll be there. They could have been assigned to oversee the jade bloods after one of the rebellions, or their lusus could have been killed when they were a grub and a Jade blood adopted them. There are plenty of loopholes to exploit.
