On the front of the birthday greeting card, imagine an epic yet humorously enchanting scene set within the grim yet wondrous universe of Warhammer 40k. In the foreground, a group of Space Marines, clad in their iconic cerulean blue armor adorned with golden trims and intricate chapter insignias, gather around an oversized, magnificently detailed birthday cake shaped like an ancient, towering cathedral. This cake-cathedra is complete with edible gothic spires and miniature candles that flicker like miniature warp-flames. Each Space Marine, including a hulking Terminator, precariously balances a party hat on their helmet, adding a touch of whimsical levity to their otherwise stoic appearance.

In the background, a colossal Dreadnought stands sentinel-like, holding an enormous balloon bouquet in its massive power claw, with balloons shaped like Tyranid heads, Ork skulls, and even a few cheerful Ultramarine symbols. Above this grandiose gathering, in the star-studded sky painted with the hues of a nebula, the words "Happy Birthday Felix" are written by a squadron of Thunderhawk gunships trailing multicolored smoke trails, forming the letters in a dazzling aerial display.

Adding a touch of humor, a servitor diligently serves colorful drinks from a plasma blaster turned soda fountain, and a tech-priest stands to the side, overseeing the operation with a servo-skull, which is wearing its own tiny party hat. Scattered confetti, gears, and mechanical bits cover the floor, suggesting a festive yet chaotic celebration typical of the 41st millennium. The overall scene captures a bizarre yet charming fusion of the somber and ceremonial universe of Warhammer 40k with the light-hearted spirit of a birthday party, all in honor of Felix.
