The idea its pretty simple. If a close combat army like blood angels can put a librarian inside a dreadnought and make it work, why the hell the mighty thousand sons, the psychic astartes chapter (no one say grey knights) cant? this would be exclusive to thousand sons and successor chapters in a maybe tzeentch demon kin codex, like khorne and probably nurgle have. Here are my ideas for a stat chart. (Disclaimer: English inst my mother tongue, expect some grammatical errors)
Battle role:
HQ 11PL/160P
M8 / WS3 / BS3 / S6 / T7 / W8 / A3 / LD8 / SV3+
A Mirage helbrute is a single model equipped with a soulreaper cannon and a ritual force axe
(idea for the axe instead of an arm)
Ritual force Axe: Melee / Melee / S+4 /
AP-4 / D3
this model may replace his soulreaper cannon with a heavy warp flamer
this model may replace his soulreaper cannon with a heavy warp flamer
(I will use similar rules to that of the chaos index, so i wont put the description for Copyright themes)
Crazed: The same of the helbrute, but you have to cast smite instead of shoot or figth.
Favoured of tzeentch T
Explodes
Psyker: Can cast 2 powers, deny 1 and knows smite and 2 of heretic discipline
Faction keywords: Chaos, Tzeentch, Heretic Astartes, Thousand Sons.
Keywords: Character, Vehicle, Helbrute, Psyker, Sorcerer, Mirage Helbrute
And some fluff: Since the times when the emperor walked among his sons across the galaxy, the crippled heroes of the adeptus astartes has been preserved for the eternity inside the sarcophagus of the mighty dreadnoughts, ready to fight for the imperium for all eternity. In the case of the thousand sons legion, such honor was granted to the wiser and most powerful of their librarians. In his natal world, Prospero, the Adeptus Mechanicus gave the legion a new model of dreadnoughts, capable of contain and preserve the knowledge and intellect of so reverenced psykers, the mirage pattern. Without the limitations of a mortal body, and instant access to the vast libraries of arcane knowledge of the imperium, this inmortal soldiers became the guardians of the most sacred piramids and places of the planet or counselors of their beloved primarch, Magnus. With the attack of the space wolves to prospero during the Horus Heresy, many of these ancient machines were destroyed defending his home or were lost forever during the long exile of the legion inside the warp. Like the entire legion, the changing forces of the empyrean also affected the remaining Dreadnoughts of the Thousand Sons, twisting this once reverenced war sarcophagus, into horrible tombs of nightmare , his once wise librarian pilots into crazed heretic sorcerers. What was an honor in past and glorious days is now a cruel punishment to any aspiring sorcerer who dares to challenge the control of his master over the cabal. The simple execution of such a valuable arcane "resource" isnt enough for an exalted sorcerer of tzeentch, who will enslave the psychic power of such a naive fool until his objectives are achieved.
So what do you think?
