Gerad is revamping Hut
John is doing crafting stuff.
Khorolf is partying and living it up.
Quinn is doing the village a service.
Connor has been preaching to the villagers the glories of Frognarok
Raven spent a 1/4 Scouting.

Well, Gerad will be finding somewhere around the village to install an Altar Of War (+1) and a Monument Of The Enduring Warrior (+2). That will let everyone effectively have +1 weapons and +2 Armor and Shields (as long as they use physical weapons, armor, and shields). That may be redundant for some characters, but should be at least somewhat useful to several of us.

He will have some infrastructure points left. Any suggestions for their best use?

Now, for the next bit of downtime... I think add Spellcraft-Boosting to Gerad's lab, add a set of Power Amplification Circles for the Shrines and Gerad's Lab, put the focus-device for the Narrative Voyager spell in the Lab, and get started on a Selune Shrine (if he has enough money).
