The Ruiduborns of it all make me feel kind of icky about a situation where they completely stop all of Ludinus’s plans. I feel like Keyleth could make speeches and other world leaders can make proclamations but there is thousands of years of prejudice the world over that exists in this world and in the lay person’s mind, the existence of Predathos proves that right. Then even further, the world is scared of Ruidusborns because the dissemination of information is very much like the Dark and Middle Ages of our world. Through the clergy, and Vasselheim needed to protect its interests, and the basic person’s knowledge of the world reflects that. All of this to say, I think the only way Ludinus’s plot doesn’t end with Ruidusborns being seen as enemy number one regardless of if he’s stopped is for the orb’s knowledge to actually be sent out. A good old Aeorian Reformation as it were.
there is a part of me that worries that this may end up in a situation like "well one GOOD ruidusborn stopped ludinus so now you jerks can't hate on them!" like a lot of situations regarding fantasy racism. they have to prove themselves to be one of the good ones to justify not having all their people killed. people can be evil or heroic regardless of their heritage, that's literally first grade, and i'm hoping that if people can see moral greyness in the gods but still respect them they can do the same for ruidusborns.
