Futhorc
Eolhx is the elk-sedge in English, the marsh plant the poem says wounds grimly anyone who grasps it. It is a defence that does nothing until something reaches for it, which is the point. This week your protection is passive and complete. You do not have to raise it, explain it or demonstrate it. Whoever takes hold uninvited finds out what the sedge is, and whoever does not never learns there was a boundary at all. Keep the marsh. Do not go looking for hands to cut.
