Shade?

It spawns every 45 minutes to an hour between 1 am and 6 am PDT.

Most bot catchers are only active outside of normal business hours because they were designed to be substitute GMs.

It won't automatically die off outside of those hours, so you'll see one later occasionally until someone comes along to kill it, but once it's killed outside those hours it won't respawn until whatrever it's set time to start watching is comes back around.

Everything except the time is right here. Shade spawns in the middle of the day EST, though I can't recall what his hours are. He and the ice witch are the only two with daylight hours.
