[Modified Human-Beast link: A technique to create a link between a human and the beast. Strength and pre-requisites for formation of link vary depending on factors such as presence of blood derived from same ancestor. If there is no such matching blood, only a suggestive link can be formed between host and a beast on the same level as host.
Modifications:
1) Formation of link in the absence of the biological organ. This modification requires a higher presence of common blood to be established.
2) Installation of back door for control of beast: This modification requires the assent of the beast in question when the link is being formed.]
This was the spell used by Daneel to form a link between Faxul and the Protector Raven, which had led the two to connect and leave the prison together.
The modifications worked like a sliding scale. If one thing was altered, then another needed to be stronger to take its place.
