Fathom is an Imperial Ocean World.[1a]
History
The planet was the site of heavy fighting during the Charadon Campaign.[1a][1b] In particular, at one point in the campaign, Fathom was invaded by a horde of Daemons led by Rotigus Rainfather. For many cycles the planet was afflicted by corrupted rainstorms that polluted the waters, corroded metal and spread diseases amongst the human inhabitants of Fathom. The Great Unclean One conjured a great, diseased mass in the planet's northern oceans that constantly spewed foul islands of filth, from which spawned the legions of Nurgle.[1b] It was left severely damaged as a result of this.[1c]
The world's defenders included Skitarii from the nearby Forge World of Metalica[2b], along with regiments of Elysian Drop Troops.[1b] The final battle of the campaign took place upon its surface as High Lord Morvenn Vahl defeated the Black Legion Lord Discordant Zeid.[Needs Citation]
Geography
A very large planet[1b], Fathom is completely covered in ocean with few or no major landmasses.[1b][2a][2b] These oceans were so deep that, despite the efforts of Explorators, an ocean floor has never been located, let alone mapped. Surveys have never even detected the planet's core.[1b]
The oceans of Fathom support abundant sea life, some of which is bioluminescent. The planet has been harvested for both water and biomatter by Metalican aqua-harvesting rigs and macro-trawlers for many centuries; despite this, the water levels on Fathom have never dropped.[1b]
