What is "interlac"

Interlac is the designated communication language of the 30th century United Planets in the DC Comics fictional universe. It is also the name of a similarly-used language in the TV series Babylon 5.

Interlac is a bimonthly amateur press association devoted to the DC Comics science fiction superhero team the Legion of Super-Heroes. It was the first APA devoted to the Legion and, despite the decline of APAs due to Internet forums, continues to operate to this day. June 2016 marked the 40th anniversary.

Interlac’s name comes from the designated communication language of the 30th-century United Planets confederation (the milieu in which the Legion of Super-Heroes operates).
