Profile

The keeper of the bramble maze of Rhosk. For twenty years she has hidden whoever runs to her in the thorn ravines: debtors, deserters, children, breakers of oaths. She is not a breaker herself; she keeps her own word and asks nobody about theirs. No one finds the cave village in the thorns unless she opens the way, and no one follows them in once she has closed it.

In their words

  • You came in by my thorns. You'll go out by them. In between, mind your feet.

Oath Tale

The Way Shut

A child reaches the thorns with a collector of the bank close behind, and the only way to keep the way shut is for Grenna to walk out through it herself.
