Gundan
From Tardis Wiki, the free Doctor Who reference
The Gundans were robots constructed by the human slaves of the Tharils.
History
Gundans could walk the timelines and were not affected by the time winds. They traveled through the Gateway to the Tharils empire, killing them and destroying their empire, allowing the humans to enslave the Tharils for their time sensitive abilities. (DW: Warriors' Gate)
