I'm tempted to just merge this into Castellan and turn it into a redirect, since it's simply another form of that title. It'd be similar to what's been done with War King and War Queen. Thoughts? – N8☎ 12:50, April 9, 2018 (UTC)
Actually, nevermind: the roles are sufficiently different to merit separate pages. – N8☎ 13:33, April 9, 2018 (UTC)
