MantiCon is a science fiction convention hosted by The Royal Manticoran Navy: The Official Honor Harrington Fan Association, Inc. (TRMN). The first four annual events were held 2015-2018 on Memorial Day weekend in Minnesota. Each year featured David Weber as the principal Guest of Honor. Additional guests varied by year, and often included David Weber's Honorverse co-authors.
MantiCon has since become the designation for TRMN-hosted conventions in other cities and at other times of the year, with a 2019 convention held in Utah.
MantiCon was conceived by TRMN founder and First Lord of the Admiralty Martin Lessem as a convention centered on Honorverse fandom and related military science fiction, drawing on the talent and experience of TRMN members to operate the event. He selected the Minneapolis area as the location because it is centrally located for US members, and because it had the largest concentration of local TRMN members.
The convention featured evening parties, a dealers' room, and multiple tracks of programming including discussion panels, author interviews, and childrens' programming. Gaming was a major component, with immersive Battletech pods and immersive spaceship bridges running Artemis Spaceship Bridge Simulator. Live entertainment included Harisen Daiko, a taiko drumming group.
TRMN's annual general meeting was held at MantiCon each year of the event, and the TRMN awards ceremony was a major event each year.
To date, MantiCon has been the largest gathering of TRMN members in one place, with members attending from at least six countries.
