A few arrows land in the snow nearby; they flew from the watchtower. A silhouette of a man leaving the tower starts approaching, holding a crossbow. The skeletons attack:

1 attacks Theren: (1d20+4)[17] hit: (1d4+2)[3] crit: (1d4)[2]
Another attacks Dain: (1d20+4)[24] hit: (1d4+2)[5] crit: (1d4)[3]
and a third attacks Robin: (1d20+4)[19] hit: (1d4+2)[4] crit: (1d4)[2]
