R5: So, after my campaign as the glorious King Aegon the VI, there is that event that makes the golden company get their ancestral lands back. So of course Duncan Strong got Harrenhal back.

The small problem is that this event came really late because i guess it requires peace time and for like 10 years straight i was never at peace due to rebellions. In that meantime, i killed almost all of the previous kingsguards and i appointed my own. Of course, that happened to include Duncan Strong.

So usually you can't grand land to kingsguards, but this event made it happen. There you go, two kingsguards. One, the regular one based on the Sword Tower led by ser Rolly Duckfield, and this one.

I don't know if they will have the same events(so far they haven't) but the succession law of the "Kingsguard of Harrenhal" says "agnatic primogeniture". The heir doesn't have the kingsguard title and so i don't know what will happen once this guy dies.
