Tambo

The tambo is the official currency of the Vamu, although not used domestically. It is a currency specifically meant to be used for external trade, and was established in 2459 XY by the Qhapui-Tahuatla. It's initial purpose was to resolve the issues of trading internationally without a single commodity which could be used for trade. Before 1459 the Vamu had used precious metals like gold or silver for trade, or used foreign currencies; this caused trouble when the Vamu expanded it's commercial activities into Acoria, where currencies from OFN-aligned nations were often not accepted.
