50 GP (five free City, two free Dungeon) - Expanded Facilities -
Your guild base includes several bits of infrastructure that normally wouldn’t be found in it.
These could include things like saunas and onsens, a marketplace, a port (for bases with
access to water, or large enough to have internal rivers), training facilities, shops for luxury
goods, high end restaurants, luxury living accomodations, or similar. You may purchase this
option as many times as you want, for as many different things you can think of. A single
purchase of an option provides enough of that particular thing to supply and support the entirety
of the guild base.
These options always seem to have enough supplies and materials to continue performing
regular business, in whatever form that might take. For options that would nominally make
money in a regular economy they will, somehow, contribute towards your Treasury, providing
your guild base with a steady supply of Yggdrasil gold coins giving you a healthy, if not
particularly impressive, amount of self sufficiency.
