Dieciocho relatos que desvelarán los secretos mejor guardados de The Horus Heresy.
De los mayores conflictos surgen los verdaderos héroes. Con la galaxia en llamas y una guerra de inimaginable magnitud arrasando el Imperio, los defensores de la luz y de la oscuridad se aventuran en innumerables campos de batalla al servicio de sus capitanes. No buscan fama o riqueza, sino enfrentarse a su destino.
Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
