Whether he tried or not is immaterial to your claim, which is that he arbitrarily decided to stop the Garleans, but not the Allagan or the Mhach, from setting up near Silvertear. You say it's a plot hole, but it's not.

1) He couldn't have stopped the Allagan Empire from moving onto Silvertear Lake. Whether he tried to or not doesn't matter. The Garlean fleet is a bunch of mere toys compared to Allagan weaponry; he got KO'd by ceruleum engines on accident / the Allagans had way more sophisticated, dangerous, and powerful weaponry than the side effects of an explosion. Yes, he probably failed or couldn't do anything about it. That's not a plot hole.

2) The Mhachi weren't threatening the world by moving into the vicinity, so he didn't need to attack them. Nor does Rowena threaten the lake by setting up shop near it. If there's not an actual threat to the font of aether in the lake, then he's not going to react.
