A living wall of albino apes was coming through the doorway. Their faces twisted in snarling expressions, showing their yellow canines but making no sound, the mute, baboon-like things began to plow through the opening. The front wave had impacted the partially open door and pushed it inward. Because they had paused outside the door and thereby lost their momentum, and because the portal was heavy and not easily moved, the beasts’ initial entry was slow. The apes behind the first wave had an opportunity to build up some speed in the corridor, and they ran over the ones in front of them. The result was that a few of the apes were stunned or injured by their allies, and the haphazard nature of the charge gave the adventurers inside the room a few valuable seconds to prepare for the onslaught.
– Chapter 12, Sea of Death, by Gary Gygax 1987
An evocative scene from the 3rd Gord the Rogue novel (the first one after Gygax’s falling out with TSR) where the heroes are attacked by a reckless horde… nay, a swarm of angry albino apelings led by “pale midgets”.
Did I say a swarm?
Hmmm… there’s an idea, an encounter with a swarm of diminutive baboon creatures in service to a mad derro savant, a subterranean living crazed albino monkey swarm.
Come to think of it, derro mobs might make the basis for a good swarm (or more likely a disorganised troop given their Small size)…
