I don't know that story, but I have not doubt it's a ridiculously exaggerated piece of ex-Arcachonian propaganda. 
Hah, very much so. A couple of Ohnarians crossed onto the Dark Isle after Velax made it clear to Me'hoe that he didn't want any there. Velax asked them to leave. They said sure, fine. One was quite polite and Velax had a bit of a chat with her. Threats weren't needed. Velax even told the Arcaeans in Ecsetuah to have their troops act normally rather than aggressively, so there'd be no battle when the Ohnarians passed through to go home.
