A juicy paradox—this place is both a temple and a bank, dedicated to Abbathor, the dwarven god of greed. Trust dwarves to mix business with divine avarice, eh? Now, the first thing you’re gonna notice as you walk up to this high-and-mighty joint are those giant unblinkin’ golem statues watching over the entrance. Massive buggers they are, carved from enchanted gemstones that could probably have financed a small kingdom. They’re not just for show neither; they can—and will—flatten a berk if they’re up to no good.
The building itself is a thing of beauty, or a monstrosity, depending on how ya feel about grandiosity. The architecture’s dwarven through and through, with lots of intricate stonework and columns that make you feel tiny and insignificant, which is probably the point. Now, the priests who run the place are as much clerks as they are clerics, devout in their calculations and stingy with their loans. Rumour has it they’re in cahoots with a cabal of dragons. Makes sense; those scaled hoarders share Abbathor’s lust for shiny things. Of course, neither party will confirm or deny this, but let’s just say you’d be a barmy to think it’s all on the up-and-up.
As for services, this place has got everything your greedy little heart could desire—loans, vaults, even investment plans tied to various planes of existence. Want invest in a promising soul trade in Baator? They’ve got ya covered. Trade Blood War diamonds with the yugoloths? Yep. But be warned: their contracts are tighter than a modron’s exhaust pipe. One wrong move, and you’ll find yourself in an Abyss (of finance, that is) that even a seasoned planewalker would struggle to climb out of. Plus, you’ll be indebted to Abbathor himself, and that sod ain’t known for his forgiveness.
So, the Bank of Abbathor Inc. — it’s the epitome of high-risk, high-reward. A fortress of wealth guarded by magics, beasts, and greedy dwarven priests. If you’re lookin’ to get richer than a githyanki pirate, this is the place to stash your ill-gotten gains. But tread carefully, cutter, for in this bank, the scales are tipped in favour of the house.
