Nordis

Gravity
Due to Nordis being a physically larger and denser world than several other planets, the majority of it's gravity is at least several times stronger which requires more force to move around. Due to this, races such as humans and asari have a difficult time moving around unaided while others such as the Krogan. This same gravity also has given the Nordians' a majority of their natural physical abilities, having forced earlier generations to evolve. However, there are certain areas of the planet where gravity is low enough that humans can move around with ease.
