Preserving Runes

High in the hills, a pair of massive stone doors stands set into a hillside, their outer markings faded under lichen, one door left a little ajar. Inside, the vault and everything in it lie untouched by time—free of dust, mold, and decay, however many centuries have passed. The stasis is anchored by hidden runes; reveal them, copy them without error, and trace them yourself, and you can preserve any room or container against ruin. The magic always takes its toll in spent vitality.
