Those three guys i save cannot be seen anywhere later on.
If you give the lighthouse cowards credit there, one of them gets a job guarding the Legion treasure chamber. The three Sparkmanster guys then disappear without a trace when they leave the cave.
If you *don't* give the lighthouse guards credit, they run to the lighthouse to see for themselves, run back out and then disappear completely. If you then save the three guys from the Sparkmaster, one of *them* gets the job guarding the treasure chamber.
A quest that ends up giving you a friend on guard gives you a prompt to check up on them.
I expect that if you screw up / screw over both sets of guards, the generic unfriendly legionnaire remains as the treasure chamber guard. I somehow can't see Blossius or Livia getting the job...
