In the era of the Lorule Invasion, which was somehow managing to successfully disguise itself as a different invasion, even though none of the participants made any sort of efforts to disguise themselves as not being from Lorule. Location - look, the topographical equivalence of transdimensional relationships is not an easy thing to calculate, okay?
Ravio was… having a bad day, to put it mildly. He was pretty sure he'd been kicked out of his home dimension - well, maybe not kicked out but he was still fairly positive that he wasn't welcome there at the moment. His Princess wasn't listening to him, which made him feel like he wasn't doing his job as an advisor. And Yuga was… existing, so that naturally catapulted things from bad to worse in the way that Yuga often made things do.
Also there was the part where his Princess actively planned to invade the next dimension over and steal their source of power. Also there was the part where Ravio felt very firmly that Hilda Should Not Do That and took it upon himself to warn the next dimension over before any lasting damage could be done. Also there was the part where Ravio was an incredible coward and really wasn't sure how he hadn't chickened out yet, because he was actually standing in the next dimension over at this very moment.
...He may or may not be panicking about all these things, but hey, at least his emotions knew what was up.
Okay. He could do this. Ravio took a deep breath and evaluated his options. He could… warn this dimension's Princess? Which would require finding the Castle, getting past the Guards, and breaking through his own inability to talk to strangers to explain to a foreign ruler that he was from a neighboring dimension that was actively planning to invade but no it's okay I'm here to warn you about it-!
Yeah, that was going to land him in prison, and Ravio did not have the mental strength to deal with prison. And that was assuming that he'd manage to make it past his crippling fear of social interaction to even get to being thrown into prison.
New plan. He could… join this dimension's Hero? Ravio felt like he had some experience in that area, it shouldn't be too bad. He'd just have to brace himself for the dungeon slogging, and the monsters... and the inevitable near-death-experiences… and… the…
Suddenly Ravio remembered why his Hero experience was limited to a single, solitary dungeon crawl. Yeah, he… he would be more of a hindrance than a help if he tried that.
New new plan. Ravio could accept the fact that the idea of any sort of hands-on assistance from his end made his voice die in his throat and his legs feel like they were going to give out on him, and offer help from a distance. He still had all the Hero Gear that his Princess had given him for the job, before he'd decided that being an advisor was a lot safer and less stressful. It wasn't like Ravio was using it, so what if he gave to this dimension's Hero instead? His stuff was all sorts of useful, the Hero would probably appreciate it.
...plus, Heroes picked up a lot of money in dungeons, didn't they? Ravio was currently flat broke, so maybe he should set up a rental service instead of just straight-up giving his stuff away. Seemed like it'd give the Hero a nice place to spend all that money he'd be picking up.
Link's latest book was titled A Savior's Companions, and it took the very odd direction of focusing not on the past Heroes, nor the past Princesses, nor even the past Conquerers, and instead putting all attention on the 'little people', so to speak, of past times. Apparently, there were quite a few invasions that would have gone off without a hitch had the civilian populace not supported the Hero. (Though, Link really wasn't sure why a Lorule native was in a book that focused on Hyrule peoples.)
"As long as you cite it properly you can get away with anything," Zelda said when Link asked her about the viability of the information.
"Good to know," Link replied, and eagerly eyed a shelf of books that he'd previously thought off-limits. Once he wrote down this newest information, he was gonna get creative.
Rule Number Thirty: All bumbling conjurers, clumsy squires, no-talent bards, and cowardly thieves in the land will be preemptively put to death. My foes will surely give up and abandon their quest if they have no source of comic relief.
