tbaMUD Continued development of the CircleMUD core

It seems complicated to me, at least. This is what I need at the moment..

When night falls, a horde (literally a horde) of zombies crawl from their graves. Likely load several mobs to each graveyard room with some type of description. They will continue to spawn in droves until dawn hits, and all of them burn away into ash with the sunlight. So when day comes, they disappear with some description.

Doable?

Sure, read helpfile on waituntil, turns out I don't have a room example but look at the others too. Room example would be easiest depending how many rooms you want the mobs in.
