Bait and Bleed - An AU War RPG

*Sirius doesn't notice. He's unpacked tools--his wand, an sextant, a pad and muggle ballpoint pen to calculate on, a small and well-worn handbook of useful charts--and now he sits, crosslegged, scribbling, looking at the sextant, adjusting it, and then flipping through the book. He hasn't even picked up his wand yet. The process of hacking a hole through a complex ward, Sirius has found, looks impressive and elegantly simple if you ignore the lengthy process of calculations, double-checks, and measurements that have to be taken beforehand.*
