Is anyone in the place still up? If I see anyone moving, I attempt a Read Surface Thoughts.
If it seems like only the innkeeper is up, I'll take the other Investigator and go tap on the door. "We'd like to ask you a couple of questions, if you've got a minute."
If it seems like someone is up who is not the innkeeper but is one of our pirates, I will again Detect Surface Thoughts.
For now, I will sit tight and wait to see what happens.
In fact, I will spend the next half-hour (assuming nothing happens to interrupt me) adding another version of Remove Fatigue to my spell list. This one will require that I speak appropriate words, though they are sotto voce, one eye closed for Odin, my left hand on my sword for Thor, my right hand on my heart for Baldur, and a single gold piece in my right palm for Loki. Loki's gold piece will be destroyed in the process. I'll put on it a requirement that it only work in a time when vigilance is significant, as on a stakeout, military patrol, forced march, or that sort of thing, and that I must be aware of that significance. It will affect everyone within thirty feet who is joining me in this endeavor (30' because I am a D&D player, and 30' is the standard radius of pretty much everything). In this particular case, everyone but the two redshirts on the other side of the building. This one will not require a Holy Ground to work, but will require that it be night (or the local equivalent thereof). This is Alliance Holy Magic, as per my usual. And... I don't think I left anything out.
It is possible that this will affect people in the surrounding buildings, if they happen to feel that they are allied to my cause of truth, justice, and the Durnian Way.
In the interest of expedience, I will not answer questions about this spell - anything that I did not cover assume results in a +0 modifier.
