=== Legio Yache 'Snow Stalkers' ===
{{Main|Legio Yache}}
Hailing from the Ice world Khellathe, the Yache, 'Snow Stalkers' are masters of percision tactics and feared for their inhuman tactical knowledge brought upon by Tzeentch blessings. Once a renowned for their knowledge and tactical prowess, the Legion fell during the Heresy, when their Grandmaster, Orthos Grulin, was confronted by a lord of change while in meditation. For three days they were locked in endless debate until, the Grandmaster came out and announced his decision, to join Tzeentch in an attempt to expand their power beyond human means.

The Legio Yache were oath-bonded to the Mastodontii Legion before the Heresy, with a Demi-Legion Maniple of 20 Engines permanently seconded to the Legion and carried in the hold of the ''Starspear'', and would continue to operate alongside them through the Heresy including on Zhuko V.
