I spent the last couple weeks letting the endgame years on my current save tick by, hoping that
something interesting would still happen in this run.
Well, it wasn't quite what I expected, but this was amusing to watch at least.
(I unlocked the L-Gates, got the Dessanu, but couldn't be arsed to attack them, being xenophile and all. Years later, the Unbidden spawned at the other end of the galaxy, directly neighboring another L-Gate, and captured the Terminal Egress. Immediately, Fun ensued for any other empire holding an L-Gate.)
