Celestial Toyroom

The Celestial Toyroom was the realm of the Celestial Toymaker, a remnant of his original home and an integral part of his existence. It was filled with toys and traps which he used to play against the opponents he brought there, including some toys who would interact with and play against his opponents. Anyone who lost the games became a plaything of the Toymaker.

It was a sliver of reality that he could occasionally step out of but never fully leave. This was a result of the rules set down for him in the childhood of the universe, (BFA: The Magic Mousetrap), presumably represented by the Ancient Covenant.

The Toymaker also resided in a "Toy Shop," though whether this was the Toyroom, another section, or another place altogether was unclear. Outside the Shop, though, was a void and the windows could repair themselves. Anyone who tried to leave the Shop entered again as if in a loop. (CC: Solitaire)

If the Toymaker ever lost a game, he would pay the price by losing his Toyroom, which would disappear. He would then have to build another, although he was all right with this as he got bored with the Toyroom after a while. He would, however, destroy the person who caused this.

The Toyroom included the Trilogic game and TARDIS hopscotch. (DW: The Celestial Toymaker)
