Elder Futhark
Algiz is the elk-sedge, and the Anglo-Saxon poem is precise about it: it grows in the marsh, it wounds grimly, it burns with blood any warrior who takes hold of it. The rune is a guard that injures whatever reaches for you. This week you are protected, and the protection has an edge. Something or someone that would take hold of you gets cut for the attempt, and you need do nothing for that to happen except stand where you stand. The instruction is not to go out looking for the hand. Sedge does not hunt. It grows in its marsh, sharp, and lets the marsh be the warning.
