Two more, from Blitzkrieg: Operation Ice Storm:
- Falcon's Beacon, a deep periphery Jade Falcon "Watch outpost" that the Ice Hellions seized in 3071 to move a massive supply convoy through, only to have a Whirlwind appear unexpectedly in the middle of the helpless convoy. One of the events that spelled doom for Clan Ice Hellion. The location is unclear and said not to be on most maps even by the Jade Falcons, but it will obviously lie between the Clan homeworlds and the Jade Falcon occupation zone.
- NGC-99382, an uninhabited system from which, after withdrawing from Camelot Command in the Dark Nebula, the Ice Hellions make the "first jump of many that would start the Ice Hellions along the Exodus Road back to home". So apparently, it's somewhere in the CJF OZ the IS or in the near periphery, presumably one jump coreward of the Dark Nebula.
Rant time:
- "NGC" doesn't denote a system. It's an abbrevation for a catalogue number in the New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC). As such, objects in the NGC catalogue are, well, clusters or nebulae or entire galaxies. That's an order of magnitude beyond a single system. The name of this star system is the equivalent of naming some back alley in a backwater town after a whole continent.
- Also, the Dark Nebula. It's pretty much treated like a single system in the story, but it isn't. It is a nebula, i.e. an area of space. In this particular case, according to canonical information, we're looking at a "vast cloud of ionized gas" with "several" white and red dwarf stars and at least 17 pulsars in it, a couple of lightyears across. Intense radiation is mentioned. Camelot Command is a planetoid orbiting one of the red dwarfs, which so far however has no name.
Other clusters in BattleTech have similar problems, lumping separate star systems together into a "cluster" for no good reason at all.
