"The beasts were like the galactic parody of dogs back on Earth. Large, muscular beasts, with dark grey skin and no fur. Reptilian and huge in size. These beasts were not fast creatures, but intelligent to a point. It was clear to her now why the krogan utilized such creatures: they were killing machines."

— Lizbeth describing a varren.

Varren (Latin: Cane Deserta, literally meaning "waste dog") is a sentient organic quadpedal species native to their homeworld of Tuchanka and of the reptilian classification. Similar to the dogs of Earth, varren are carnivorous animals that naturally roam the nuclear wastes of Tuchanka hunting for food. After the krogan introduction to the galactic community, the varren have spread to numerous worlds, and the batarians use them as war hounds. The varren, like any other dog, can be tamed, but it is extremely difficult.
