Polaris and Sirius are brother and sister (Sirius on the left and
Polaris on the right). They are genetically very similiar and are almost
the same size, sharing many features although it is not hard to tell
them apart. They are also naturally born Proteus ships, much like Saya
was.
They are typical kids, learning, playing and fighting a bit too.
These
two are set to make their debute in Proteus Unbound Book 7, the first
book of the Legacy Saga and to say readers will have a rollercoaster
ride is an understatement when you meet these two.
