S is for Sanctum Cometus.
Batman has the Batcave; Superman his Fortress of Solitude. The Tick has Arthur's apartment.
For the Crusading Comet, it's the Sanctum Cometus.
A secret, high-speed elevator inside Warren Kensington's penthouse leads to the Crusading Comet's hidden lair, a cavernous compound with high-tech equipment, research lab, workout facilities, guest quarters, and much more. It's where the Comet makes his wonderful toys and observes the world around him. Few are allowed inside.
Of course, it's entirely possible there are more than one, but the Comet isn't telling.
