The companions jerk to attention as the sunrod illuminates the back of the warehouse. 20' up above them they can see their prey, attending to squeeze through a small hole near the ceiling. It is almost through the opening. Tumna, being the least encumbered and with the longest legs, has outpaced the cleric and the dwarf.
You estimate you have one round to act before it crawls out. Tumna is about 10' away, Eddy and Borkel 20' away. On the previous combat map, the creature is about on square K30. Tumna is on I29, Eddy on J26, Borkel on L26.
