"We don't know why it's getting worse. The likeliest explanation is that a powerful entity within Abaddon decided to put more effort into expansion into the Material world. We don't know if they were prompted by anyone from here, or decided on their own, or why now in particular. We're monitoring the situation, but we don't have an army out there -
- we don't, actually, have a standing army at all. We have a series of agreements with the holy orders, guilds, mercenary companies, and so on of Osirion to participate fully in the national defense should we be invaded. If I threw an extraordinary amount of effort at those agreements I could renegotiate them, but I prefer not to. I wouldn't just be giving myself more options but every pharaoh of my line, and anyway there are some options it is worth taking off the table to save ourselves and our neighbors the expense of constantly preparing for a war.
That leaves us fewer options for responding to Thuvia's problems while they remain entirely confined to Thuvia; we could still assemble and send a force of some kind, but they wouldn't be enough to be decisive, and we don't like committing indefinitely to an effort we can't win. We do have people there keeping an eye on it, of course. We can and would send a force if someone were attempting to coordinate an international response on the general principle there should be an international response to planar incursions - you've got no business being a Lawful country if you can't coordinate like that - but the likely candidates to arrange something like that are all wrapped up in the fight against the Worldwound.
Also the church of Nethys is opposed and Nefreti is the person most likely to successfully design and implement a permanent solution so I'm not thrilled about alienating her over it."
