Razorgore the Untamed Quest Behaviour help

[Uhtred]

Hi im in the process of making a Blackwing Lair profile for Neutral transmog farming that i'd like to share with the community but to complete it I need a quest behaviour for Razorgore. I have no idea how to make a quest behaviour and cannot find any info on making one for myself. If anyone could help or advise in any way it would be much appreciated. Many thanks
