The heart of Tír Idir

Victory without erasure

Memory has weight

Names, promises, and old harms shape what people can become.<br>Remembering is a responsibility, not a weapon reserved for the<br>powerful.

Mercy has consequences

Rivals are not faceless evil. Clann Dorcha, tainted beings, and<br>those touched by Fomorian power still carry motives, bonds, and<br>the capacity to choose.

Thresholds require consent

Sidhe roads, geasa, and oath-stones ask who may cross, who may<br>bind another, and whether tradition can remain sacred without<br>becoming coercion.

Responsibility is chosen

The Fifth Peace does not promise easy harmony. It asks each<br>person and clan to choose what they will repair, protect, and<br>remember together.
