I do not have a direct answer to your question, however one thing about Sheru that I have always felt from the docs to be true is his followers are insane, just as insane as possibly Zelia's. Sheru has chosen his and pushed insanity on them, where zelia's give there mind freely and ask her to accept them. I rarely see either one of these Arkati's followers include the fact there minds are not stable in the daily R/P they choose. Probably more so with Sheru, as there are other facets to him to make him attractive as an Arkati. Myself, I generally expect to see followers of either should have some element of instability and to say the least odd or erratic behavior.
