Fathom was created by Michael Turner, who said that he found the inspiration from an issue of National Geographic.Wizard "Wizard Special: Fathom and the Top Cow Universe" (1999). p. 15. The first series began in 1998 and was abruptly halted in 2002 when it was discovered that Turner had been diagnosed with cancer. During the period of inactivity on the main series, comic book artist Talent Caldwell drew a miniseries titled Fathom: Killian's Tide. After Turner's cancer went into remission, he left Top Cow and launched his own company, Aspen MLT Inc. During this period there was a legal conflict between Turner and Top Cow as to who owned the rights to Fathom.
