I've been looking at every single ancestor of Irithia for several hours and I'm getting extremely sick of it now so I'm going to take a break, but I've found 42 ancient ancestors so far. I'm going to list all the lineages here, but if you want me to edit them out so they don't clog up the thread, please let me know and I can just list the ancient dragons.
