Any dungeon that can be cleared can serve as a guild base.

In a game the size of Yggdrasil, there were presumably tens of thousands such dungeons that were on the extreme low-end, basically culverts with rats in them which then offered you 10 levels of custom NPC data etc. Indefensible if anyone else happened across it, but not like you'd have much of real value there.

It is probable that at least some of the players in the 7 known Advent waves have been from such minicule guilds that they basically were indistinguishable from solo players.
