Editing Ashes of Yggdrasil (section)

===Available Biomorphs===
The highly erratic nature of the Nidhoggr hive fleet differentiates it from other tendrils. Due to the intrinsic nature of the biomorphs present, the smaller types such as gaunts and genestealers wouldn't be able to survive the extreme internal heat. For this, the Norn Queen known as the Molten Empress privileges bigger organisms and has adapted new strains to fill the gaps of the discarded specimens.

While creating a {{W40kKeyword|Nidhoggr}} army, you may not include any of the following units:
''Broodlord'', ''Old One Eye'', ''The Swarmlord'', ''Gargoyles'', ''Hormagaunts'', ''Termagants'', ''Genestealers'', ''Pyrovores'', ''Parasite of Mortrex'', ''Ripper Swarms'' and/or ''Sky-slasher Swarms''.

You may instead include the following units:
''Garmriex'', ''Linnorm'', ''Surtr-Class Swarmlord'', ''Suam'O'', ''Ignis-Class Pyrovores'', ''Wyrm Swarms'' and/or ''Magma Corer''.
