1) His most common shape looks like a white anthropomorphic ragdoll rabbit in a jade-green velveteen servant's attire, with a winged silver pocket-watch that he constantly checks. He has a silver brooch that features three rabbits chasing each other in a circle, and each of the ears is shared by two rabbits, so that only three ears are shown. In this form (which is more {{Aspect|Moth}}), he a servant of the Velvet Vidame, but he is always trying to be a nuisance for him, however petty and insignificant it may be, undermining the Vidame's authority and ridiculing him when possible. The Valet is a messenger of the Atelier, perpetually in a hurry, used to relay the Modiste's and her Names' messages, and often a guide for the dreamers and other guests visiting the Atelier. He is known to plot his master's downfall as the member of the Autumn Salon, which he usually attends in this form.

2) In this form (equally {{Aspect|Moth }} and {{Aspect|Grail}}) he has a straw wreath on his head, his brooch is still present, and sometimes he is seen with a mortar and a pestle, grinding herbs and tea leaves to prepare them for consumption. He mockingly mimics the Velvet Vidame in mannerisms, behaviour, and appearance, and conducts his distracting feasts and tea parties in the Spring Salon, specifically to disrupt any discussion happening there by the merrymaking and ungovernable whimsy, with the ultimate goal of undermining the Vidame and eventually overthrowing him. The two used to be in love, but the Valet was betrayed by his unfaithful lover, and now he is heart-broken and bent on revenge. He is often accompanied by many rabbit-like Mansus spirits (or perhaps simple illusions - no one is sure) that he claims to be his children. He is in the Modiste's good graces, since he sacrificed himself to sustain her during her separation from the Spindle. She brought him back, but his power was severely diminished, and the feasts partially serve to help the Valet recover, while the Modiste is known to attend in her free time.

3) The Volpertinger, the Horned Hare, the beastly form (more {{Aspect|Grail}}) that he takes to hunt so that he can sustain himself; a feral werewolf-like hare with gnarly, branching antlers, claws and sharp fangs. The feasts often happen after his hunts, which isn't a coincidence. The hunting dogs of the Fleeced Foyer - Orion's hunting dogs? - are the Valet's mortal enemies. They sometimes engage in fights when the Valet hunts, and it is not always clear who is the prey.
