{Landowner, Hoard of 100,000 gp} Boon of the Dungeon Lord

Prerequisite: Must own a building and have a horde of over 100,000g there
Title Gained: Lord of __
Your building and horde are so amazing word starts to spread, creatures attuned to your alignment will come to serve and live in the new dungeon, you gain lair actions inside and regional effects (determined by your alignment, the building location etc), and teams of enemies not of your alignment will come to attack your dungeon, possibly bringing you even more treasure and fame.
As your dungeon kills more and more enemies its fame grows, perhaps even more than the most famous of dungeons like the Tomb of Horrors
