Cassandra moves back to help the fallen guard.
Titus fires another energy blast, but it's deflected by the bone shield (did not hit target AC).
Another piece of bone flies at Chloe, hitting her with a heavy thud. The skeleton moves out of sight behind a building as it retreats due to heavy damage.

The rest of the night passes without any major issues on your area of the wall, although Titus is briefly pulled away to help heal a couple of other injured guards somewhere else.
Cassandra comes off the walls around 4am to trance, and by 8 in the morning, the sun is up, and everyone is rested and ready to depart.
Anything final before you head out from Veros? Do you request any supplies from them? Where do you go?
