Master Steven, would it actually be possible for Haegon and Ser Aegor Rivers to make their way into the Reach from Yronwood territory without serious fighting? (as I understand the Geography the Bloodroyal only controls passes through the Red Mountains that lead into the Stormlands – being in the Northeast of the Principality – which would make it at least POSSIBLE they might prefer to detour via Sumemrhall, meeting assets from the Reach and the Marches there, rather than run the gauntlet).
