Suppose I'm at one room and gowron is at another. I want to say to
gowron "come to me". Wouldn't it be strange to say {HIjaH} "go to me"
? In this case shouldn't I say {HIchol} or {HIghoS} ?

In English it's strange because we have the different words go and come, which imply motion away from (or unrelated to) and toward the speaker. We don't have this split in Klingon, and we have little data about whether it would be strange to Klingons. We know that HIghoS has been used a couple of times, but HIjaH and HIchol have not. (I don't think HIchol would be used for this anyway, since the point isn't to make your distance to me less but to come to the same room as me.)
