Razina is not particularly strong in the One Power. Her level of strength is described by "The Wheel of Time Companion" as 28(16) which is a middle level in Aes Sedai hierarchy. With this level of strength she is unable to open alone a suitable gateway to Travel.
She has remained loyal to the White Tower during the split.
Razina was one of the captured Aes Sedai to be interrogated by Verin Mathwin in order to discover the White Tower's intentions towards Rand al'Thor. In reality Verin used her mild Compulsion to implant in their minds some instructions about Rand.
Particularity of this characterEdit
Razina Hazzan is described only in The Wheel of Time Companion, she is never mentioned in the main books of The Wheel of Time. Taking inference from the Companion, she is the second Brown sister mentioned in the party sent to kidnap Rand in Cairhien.
But this is in contradiction to the description of this group in the main series, because we know well the number of sisters and the Ajah involved in the kidnapping group and no more Brown sisters than one (Nesune) were ever counted in that party.
