I wonder why they'd leave their home systems? There's no reason to suspect there's anything out there that they can't make close to home - presumably it's all just mass and energy (which are on some level the same thing anyway). Depending on the type of star they live around (seems like a fair assumption they need a star for energy), it'll run down quickly or slowly, but so will every other energy source in the universe. That is to say that I think the answer to the Fermi Paradox is simple, everyday Nihilism.
