Gabomba in the past is run by Gor-Kazkwanbwe, and is a bit more peaceful than it's present version. Some differences are that: the ruined steeple is competly intact, the undead don't roam the streets, and the sky isn't bathed in a perpetual twilight.
The town is also a bit larger, because the graveyard of the present is actually part of the town. The southern part of town consists of some more huts (unlike the Twilight-town cottages of the present) as well as a weapons/armour shoppe.
Gabomba's Past graveyard is in front of the Steeple, which is used as the temple. (meaning that the Shrine in the present also does not exist)
