A volcanic planet in Týr about the size of Mercury, Arae's atmosphere is composed of 32% Hydrogen, 28% Oxygen, 7% Nitrogen, 13% Helium, and 20% Krypton. The FTS Navy mines iron, gold, and other essential metals from its crust, which appears to be rich in useful metals and minerals. It is also speculated that the FTS navy has at least one secret research facility on the planet, as its harsh environment and geo-political position keep all others away.
