Anchor of a life blood

The Anchor of a life blood was used by a Shadow Kin consultant, Rannus, in order to try to force Corakinus' heart to stay in his body, rather than swap between his and April's. However, the anchor failed and an enraged Corakinus executed Rannus.

Corakinus' next consultant, Kharrus, also suggested they used the anchor. He commented that Rannus had been "too cowardly to go the extra step" and explained that they could attach Corakinus' whole body to the anchor rather than just his heart. This meant that wherever the heart went Corakinus would go with it, although there was a risk that the heart could be torn in two which would kill both Corakinus and April. After believing the anchor had failed again Corakinus executed Kharrus but later discovered that the experiment had succeeded and used the anchor to open a crack in time leading to Earth.
