Umbral Veil

When the path vanished between flame, frost, storm, and shadow, Umbra taught the Shinobi to become the bridge.

The hidden blade did not ask the world for permission, only for a moment no eye could keep.

Thus the veiled were taught to release darkness between elemental signs, striking where pursuit had already lost its name.

For the surest art is the one remembered only after it has disappeared. - Codex Umbra
