I'm building a world in a nation role-play community. I recently have begun to use ftl technologies (ftl information transfer and travel) while the majority of the community has had ftl technologies for dozens of millenia. My world does not employ the use of violence or employ weapons. The interstellar ships used are not built with weapons and weapons have not and will not be developed. I do wish to aid in potentially violent happenings and not become a target whenever my nation appears. Infact I would like almost the opposite to occur. How does one impose a sense of intimidation without the use of violence or weapons?

I would like the reaction to the appearance of one of my nations navies to elicit a feeling of dread or fear for whatever reason you, the answerer generates.
