[sblock=OOC] My take on this (other ideas welcomed):
>What we do before leaving: (As a group) nothing, just head out. Since we're camping right at the entrance, it isn't likely anything will sneak in past us, so any traps or locks we activate won't hinder anyone except us.
(Personally) As noted, Sweetness will spend one HS for our initial short rest, leaving her with one. She will also lay claim to one of the kenku corpses, in an effort to determine if they do taste like chicken.
>What we do to protect ourselves: Seal the hatch once we leave, camp inside the ruined tower. Two people per watch shift- one watching the hatch/entry, one at the exit from the tower to outside looking outwards (and switch the two positions fairly regularly within the watch shift. Keep a small fire, with wood nearby if needed (we are in a forest, so that shouldn't be tough).
>Watch order: three shifts, two per shift- hopefully at least one with a good Perception. Sweetness will take first watch- who else wants to choose a spot? (Otherwise we can assign them) [/sblock]
