That being said, the Vagrants and K'Hara differ only 23/24 years. If you remember the hypergate scene from mission 13, you see not only small ships getting sucked into the hypergate but also Marduks (some of them even getting destroyed by that, by the looks). We've been there for as long as K'Hara, meaning we do have elder entities as well. They may or may not be in Sirius by now, even.
